5, 10, and 20 are all multiples of 5 and factors of 20.
No. A factor is a number or algebraic expression by which another is exactly divisible. A multiple is a number that can be divided by another number without a remainder. Factors go into numbers, numbers go into multiples.
There are infinetly many numbers which have 2 and 5 as their factors. Some examples are 10, 20, 30, 40, etc. 2 and 5 both are prime numbers and their common multiples are the multiples of 2 x 5 = 10. So all the multiples of 10 have 2 and 5 as their factors. However if consider 2 and 5 as the only two proper factors, then the required number is 10.

It's false because there are other numbers ending 0 being multiples of 5.
There are three numbers between 10 and 50 which are divisible by both 3 and 5. All numbers that are multiples of 3 and 5 are the multiples of the lowest common multiples (lcm) of 3 and 5 which is 15. The multiples of 15 between 10 and 50 are {15, 30 and 45}, thus there are 3 numbers.
Multiples. The numbers 10, 15 and 20 are multiples of 5.
Multiples of 10.
Multiples of 10
5, 10, 15, 20
5, 10, and 20 are all multiples of 5 and factors of 20.
Numbers which are the factors of thirty and multiples of five are 5, 10, 15 and 30.
Numbers ending in zero are all multiples of 10, and therefore also are multiples of 2 and 5.
Multiples of 10.
5, 10, 25, 50
Well, honey, common multiples of 5 and 10 are numbers that both 5 and 10 can divide evenly into. So, grab your calculator and start counting by 10s until you hit a number that is also divisible by 5. Spoiler alert: the first few common multiples are 10, 20, 30, 40... you get the idea. Happy math-ing!
Factors of 10: 1, 10, 2, 5 Multiples of 5: 5, 10, 15, etc. From this, we see that 5 and 10 are factors of 10 and multiples of 5. Therefore, there are two numbers that are factors of 10 but not 5. They are: 1 and 2
