common factors, the greatest common
factor, and prime factorization. Factors of 6
First, have the students find the factors of the 12345678
given numbers.
Find the factors of 6 in the number, 1-8. 6 is divisible by 1, 2, 3, and 6.
Find the numbers that divide 6 equally. So, 1, 2, 3, and 6 are factors of 6.
Divide 6 by each of the numbers starting
from 1. Find the factors of each number and circle them.
Have the students divide 6 by the numbers
from 1 to 6. Guide them to finding that 6 Factors of 8 Factors of 10
cannot be divided equally by 4 or 5.

Which numbers can 6 be divided by
equally? 1, 2, 3, 6. Factors of 12 Factors of 14
Numbers that another number can be
divided by equally, are factors. What are 123456 123456
the factors of 6? 1, 2, 3, 6. 7 8 9 10 11 12 7 8 9 10 11 12

2. Build Understanding
When finding factors, students may have difficulty in identifying what numbers to divide the given number
by. If the number is 8, have the students divide by the numbers from 1-8, if it is 14, then the numbers from
1-14, and so on.
Example: Factors of 14
Divide 14 by the numbers from 1 to 14. Find the numbers that divide 14 equally.
14 1 14, 14 2 7, 14 3 4r2, 14 4 3r2, 14 5 2r4, 14 6 2r2, 14 7 2,
14 8 1r6, 14 9 1r5, 14 10 1r4, 14 11 1r3, 14 12 1r2, 14 13 1r1, 14 14 1
The factors of 14 are 1, 2, 7, and 14.
