12 is a multiple of 2.

A multiple is found by multiplying the number. Whereas a factor is what the number can be divided by. For example - multiples of 10 are; 10, 20, 30, 40, ... Factors of 10 are; 1, 2, 5, 10

2 is the lowest common multiple of the two but 4 also goes into them both.

3 and 9 both work

The LCM of 35 and 40 is 280, which is the multiple of the combined prime factors of both numbers (2 x 2 x 2 x 5 x 7).

2 is the only number is that both a factor of 2 and a multiple of 2.

1, 2, 5, 10

40 Least Common Multiple for two numbers is a number that is divisible exactly by both of the 2 considered numbers. Since 40 here is a multiple of 5, 40 is the smallest number that is divisible by both 5 and 40.

The LCM of 8 and 10 is: 40Start by showing some multiples of both numbers:Multiples of 8: 8, 16, 24, 32, 40, 48, ...Multiples of 10: 10, 20, 30, 40, 50, ...The lowest common multiple is the lowest multiple that these two numbers have in common, making 40 the lowest common multiple in this case.Another way of doing this is to factor both of the numbers and multiply factors (skipping redundancies):8: 2, 410: 2, 52*4*5 = 40The LCM is 40.

The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40. So yes 5 is a factor of 40.

3 and 9 both work

The numbers 2 and 6 meet both conditions.

its both. in the problem 8*2=16 8 is a factor. 2, 4, 6, 8, 10, ect. its then a multiple. so it all depends on your problem

1 is a factor of 4 that is not a multiple of 2.

1, but i think you either mean least common multiple (40) or greatest common factor (2)The LCF is 1. The GCF is 2. The LCM is 40. The GCM is infinite.

factor both numbers factor 40 into [2 2 2 5] or [2^3 * 5] factor 100 into [2 2 5 5] or [2² * 5²] LCM is the highest power of each common factor 2^3 * 5² = 8 * 25 = 200 ◄

6 is a factor of 30 and a multiple of 2.
