First approach factor 1750
Go in steps
10*175
(5*2) * (5*35)
5*2*5*7*5 = 1750 So these are the factors
Then you figure out how many prime numbers between 1 and 100 there are by seeing that there are 3 prime factors
2, 5 and 7
Any other factor of 1750 would have to itself be factorable into some combination of these three numbers so that would mean they couldn't be prime.

Accordind to my calculator 1750= 2*5^3*7, so the prime numbers that are factors of 1750 are 2,5,and 7.

Let's factor 1750
1750/2 = 875
875/5 = 175
175/5 = 35
35/5 = 7
7 is prime.
So 1750 = 2*5³*7
and the answer to your question is 3 primes: 2,5 and 7.
