All numbers that have 9 as a factor also have 2 as a factor?

True or False

False.

Numbers with factors of 9:

18, 27, 36, 45, 54, 63, 72, 81

18, 36, 54 and 72 may have factors of 2, but the other do not.

This means that not all numbers with 9 as a factor will also have 2 as a factor.

False

For example factors of the number 9:

1, 3, 9

9 has 9 as a factor but not 2
