Saxon Course 2: Lesson 6 (Slides)

Lesson 6

• Factors

• Divisibility

​Factors

​Greatest Common Factor (GCF)

​Divisibility

• Divisibility: a number divides the given number without any remainder, and the answer is a whole number.

• Example: 12 can be divided by 3 to get 4. So we can say 12 is divisible by 3.

​Tests of Divisibility

• There are several methods for testing the divisibility of a number without actually dividing! Here are a few:

a number ending in...

one zero is divisible by 2.
two zeros is divisible by 2 and 4.
three zeros is divisible by 2, 4, and 8.

​Daily Challenge #6
pick one to answer:
a. List all the common factors of 12 and 20. Then circle the GCF (greatest common factor).

b. The number 7,000 is divisible by which single-digit numbers?
