Is 370 a prime number?
It is possible to find out using mathematical methods whether a given integer is a prime number or not.
For 370, the answer is: No, 370 is not a prime number.
The list of all positive divisors (i.e., the list of all integers that divide 370) is as follows: 1, 2, 5, 10, 37, 74, 185, 370.
For 370 to be a prime number, it would have been required that 370 has only two divisors, i.e., itself and 1.

Actually, one can immediately see that 370 cannot be prime, because 5 is one of its divisors: indeed, a number ending with 0 or 5 has necessarily 5 among its divisors. The last digit of 370 is 0, so it is divisible by 5 and is therefore not prime.
As a consequence:
- 370 is a multiple of 1
- 370 is a multiple of 2
- 370 is a multiple of 5
- 370 is a multiple of 10
- 370 is a multiple of 37
- 370 is a multiple of 74
- 370 is a multiple of 185
For 370 to be a prime number, it would have been required that 370 has only two divisors, i.e., itself and 1.
Is 370 a deficient number?
Yes, 370 is a deficient number, that is to say 370 is a natural number that is strictly larger than the sum of its proper divisors, i.e., the divisors of 370 without 370 itself (that is 1 + 2 + 5 + 10 + 37 + 74 + 185 = 314).
