Answer:
1750 = 2 · 5³ · 7
Step-by-step explanation:
It is often helpful to start with divisibility rules when finding prime factors of a small composite number.
The least-significant digit is even, so we know 2 is a factor.
1750/2 = 875
The least significant digit is 5, so we know 5 is a factor.
875/5 = 175
175/5 = 35
35/5 = 7
7 is a prime number, so we're done.
The factorization is ...
1750 = 2 · 5³ · 7
