35 and 70 both have 7 and 5 as prime factors
This needs more information. Generally, questions like this read, "What are the common multiples (of certain numbers) that are under 50?" Example: 3 and 5 The common multiples of 3 and 5 that are under 50 are 15, 30 and 45.
Chances are: 4 out of 50
Multiples of 5 are 5, 10, 15, 20, 25, 30, 35, 40, 45, 50... Multiples of 10 are 10, 20, 30, 40, 50, 60, 70, 80, 90, 100... The pattern is that every other multiple of 5 is also a multiple of 10.
25, 50, 75, 100, 125, 150, 175, 200, 225, 250, 275, . . .
Multiples of 50 are the only numbers that are both. All other multiples of 5 aren't.
All of those numbers have an infinite amount of multiples.
50 is an even number so ALL its multiples are even...
what are the multiples of 50
6,12,18,24,30,36,42,48
56, 63, 70 and 77
No 50 does not
Since 10 is a multiple of 5, all multiples of 10 will also be multiples of 5. Test the theory. 30, 50, 100... All multiples of 10, and also of 5.
56,64,72,80,88,96
56,63,70,77,84,91,98
35 and 70 both have 7 and 5 as prime factors
The factors are 1, 2, 5, 10, 25, and 50. There are an infinite number of multiples starting with 50, 100, 150, 200, 250, 300, etc.
