The factors of 2 are 1 and 2 because 2 divides by 1 and 2
The factors of 3 are 1 and 3 because 3 divides by 1 and 3
The factors of 4 are 1, 2 and 4 because 4 divides by 1, 2 and 4
The factors of 5 are 1 and 5 because 5 divides by 1 and 5
The factors of 6 are 1, 2, 3 and 6 because 6 divides by 1, 2, 3 and 6
The factors of 7 are 1 and 7 because 7 divides by 1 and 7
The factors of 12 are 1, 2, 3, 4, 6 and 12 because 12 divides by 1, 2, 3, 4, 6 and 12
So, 1 is a factor of any number?
Yes
number divided by 1 = number
number ÷ 1 = number
So, yes, 1 is a factor any number.
So, any number is a factor of itself?
Yes
number divided by number = 1
number ÷ number = 1
So, yes, every number is a factor of itself.
Also, have I understood this correctly,
if a first number divides by a second number
then the second number is a factor of the first number?
Yes
2 divides by 1 so 1 is a factor of 2
6 divides by 3 so 3 is a factor of 6
20 divides by 5 so 5 is a factor of 20
So, is a factor of a number, either
the number itself
OR
another number which the first number divides by?
Correct.
If I say to myself
"multiply to get a multiple
divide to test for a factor"
will I have the correct idea?
Yes
