2, because when you simplify 4/8, you get 1/2, which has a 2 just like 2/9.
Common factors are those that can be divided into two different numbers. For 4 and 40, their common factors are: 1, 2, 4, -1, -2, -4. Of these, the largest number is 4 (and this is therefore the greatest common factor).
A prime number can only be divided by itself and 1. 4 can be divided by 2 26 can be divided by 2 15 can be divided by 3

a common denominator is a number that 2 numbers can be divided by evenly, 8 and 12 are both divisible by 4 and 2 and 1, so those are their common denominators. Normally you would need 2 numbers to get a common denominator, but because 19 is a prime number, (which means it can only be divided by 1 and itself 19) then no matter what other number is paired with it, there will only be 1 common denominator and that is 1

A number divided by 2 its reminder is 1, A number divided by 3 its reminder is 2, A number divided by 4 its reminder is 3, A number divided by 5 its reminder is 4, A number divided by 6 its reminder is 5, A number divided by 7 its reminder is 6, A number divided by 8 its reminder is 7, A number divided by 9 its reminder is 8, A number divided by 10 its reminder is 9 what is that number?
Not necessarily. 1 1/2 divided by 2 = 3/4. 4 1/2 divided by 2 = 2 1/4.

1 is the least common factor of the number 2, number 4 and number 7. 28 is the least common multiple of the number 2, number 4 and 7.

can be divided by 2 and aren't prime.
The difference that when divided by 2 does not give a whole number is the odd one. For example, 6-2=4 , 4 divided by 2=2 , 2 is a whole number; so 6-2 is not odd. 5-4=1 , 1 divided by 2=1/2 , 1/2 is not a whole number; so 5-4 is odd.
