30, 50, 60 70 and so on.
They are: 5, 10 and 20
The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80 Those which are multiples of 4 are: 4, 8, 16, 20, 40, 80
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.
What are the odd multiples of 3 between 10 and 40? 15, 21, 27, 33, 39. What multiples of 10 is 34 between?
2 and 5 are the prime factors that are common to all multiples of 10.
no 4,5 and 8 are factors of 40
40 is the least number that is a multiple of 4 and 10. all multiples of 40 are multiples of 4 and 10 as well
No number has the multiples of 1, 2, 4, 5, 8, 10, 16, 20, 40, 80, but the number 80 (and all its multiples: 160, 240, 320, 400, ...) has them all as FACTORS.
No.
This is a nonsensical question. There are more than 13 multiples of 10 - in fact there are an infinite number. And there are multiples of 10 which have an infinite number of factors - so there cannot be a "largest" number of factors.
Multiples of 5 and 10 are called common multiples.
The first 4 multiples of 10 are: 10, 20, 30, and 40.
