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
All factors of 16 will also be factors of all multiples of 16. Multiples of 16 will also have factors that are not factors of 16. For example, 80 is a multiple of 16, but some of the factors of 80, like 5, 10, 20, 40 and 80 are not factors of 16.
It depends on what they are compared to. In general, factors will be smaller than the number they are compared to, and multiples will be larger. Overall, factors tend to be smaller than multiples, but 20 is a factor of 40 and 10 is a multiple of 5, so there are exceptions.
Factors go into numbers, numbers go into multiples. The factors of 20 are 1, 2, 4, 5, 10, 20 The multiples of 20 are 20, 40, 60, 80, 100 and so on.
No.
no 4,5 and 8 are factors of 40
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.
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
10, 20, 30, 40...
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.
