Composite Number

• A whole number that can't be made by multiplying other whole numbers.

  Example: 5 can be made by 2 × 3 so is a composite number.

• A whole number that can be made by multiplying other whole numbers.

  Example: 6 can be made by 2 × 4 so is a composite number.

• A whole number that can be made by multiplying other whole numbers.

  Example: 17 can be made by 2 × 3 so is a composite number.

• A whole number that can be made by multiplying other whole numbers.

  Example: 6 can be made by 2 × 3 so is a composite number.

Prime Factor

• A factor that is a prime number.

  
  

  In other words: Only one of the prime numbers that can be multiplied to give the original number.

  
  

  Example: The prime factors of 15 are 3 and 5 (because 3×5=15, and only 5 is a prime number).

• A factor that is a prime number.

  
  

  In other words: any of the prime numbers that can be multiplied to give the original number.

  
  

  Example: The prime factors of 15 are 3 and 5 (because 3×5=15, and 3 and 5 are prime numbers).

• A factor that is a prime number.
  
  In other words: any of the prime numbers that can be divided to give the original number.
  
  Example: The prime factors of 15 are 3 and 5 because $3\div5=15$

• A factor that is a prime number.
  
  In other words: any of the prime numbers that can be added to give the original number.
  
  Example: The prime factors of 15 are 3 and 5 (because 3 + 5=15, and 3 and 5 are prime numbers).

Factor

• Numbers we can multiply together to get another number.

  
  

  Example: 2 and 3 are factors of 6, because 2 multiplied by 3 = 6

  
  

  A number can have MANY factors!

  
  

  Example: What are the factors of 12?

  • 3 multiplied by 4 = 12, so 3 and 4 are factors of 12

  • 2 multiplied by 6 = 12, so 2 and 6 are also factors of 12

  • and 1 multiplied by 12 = 12, so 1 and 12 are factors of 12 as well

• Numbers we can multiply together to get another number.

  
  

  Example: 3 and 7 are factors of 6, because 3 × 7 = 6

  
  

  A number can have MANY factors!

  
  

  Example: What are the factors of 12?

  • 3 × 8 = 12, so 3 and 4 are factors of 12

  • 2 × 4 = 12, so 2 and 6 are also factors of 12

  • and 1 × 10 = 12, so 1 and 12 are factors of 12 as well

• Numbers we can subtract together to get another number.

  
  

  Example: 2 and 3 are factors of 6, because 2 - 3 = 6

  
  

  A number can have MANY factors!

  
  

  Example: What are the factors of 12?

  • 3 - 4 = 12, so 3 and 4 are factors of 12

  • 2 - 6 = 12, so 2 and 6 are also factors of 12

  • and 1 - 12 = 12, so 1 and 12 are factors of 12 as well

• Numbers we can divide together to get another number.

  
  

  Example: 2 and 3 are factors of 6, because 2 divided by 3 = 6

  
  

  A number can have MANY factors!

  
  

  Example: What are the factors of 12?

  • 3 divided by 4 = 12, so 3 and 4 are factors of 12

  • 2 divided by 6 = 12, so 2 and 6 are also factors of 12

  • and 1 divided by 12 = 12, so 1 and 12 are factors of 12 as well

Define quotient

• The answer after we divide one number by another.

  
  

  dividend ÷ divisor = quotient.

  
  

  Example: in 12 ÷ 3 = 4, 3 is the quotient.

• The answer after we divide one number by another.

  
  

  dividend ÷ divisor = quotient.

  
  

  Example: in 12 ÷ 3 = 4, 12 is the quotient.

• The answer after we multiply one number by another.

  
  

  dividend x divisor = quotient.

  
  

  Example: in 12 x 3 = 4, 4 is the quotient.

• The answer after we divide one number by another.

  
  

  dividend ÷ divisor = quotient.

  
  

  Example: in 12 ÷ 3 = 4, 4 is the quotient.
