02/01 AM: GCF, LCM, Distributive Property

Front

What is the least common multiple (LCM)?

Back

The least common multiple (LCM) of two numbers is the smallest multiple that is evenly divisible by both numbers.

Front

What is the greatest common factor (GCF)?

Back

The greatest common factor (GCF) of two numbers is the largest number that divides both of them without leaving a remainder.

Front

How do you find the LCM of two numbers?

Back

To find the LCM, list the multiples of each number and identify the smallest multiple they have in common.

Front

What are factors?

Back

Factors are numbers that can be multiplied together to produce another number.

Front

List the factors of 12.

Back

1, 2, 3, 4, 6, 12

Front

What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac, meaning you can distribute a number across a sum.

Front

Use the distributive property: 3(4 + 5) = ?

Back

3(4 + 5) = 3*4 + 3*5 = 12 + 15 = 27.

Front

What is an example of a problem that cannot be solved with factors?

Back

If you need to arrange 36 corn stalks in 2 rows, you cannot have 12 corn stalks in each row because that would require 24 stalks.

Front

What is the relationship between GCF and LCM?

Back

The product of the GCF and LCM of two numbers is equal to the product of the numbers themselves.

Front

Find the GCF of 8 and 12.

Back

The GCF of 8 and 12 is 4.
