The numbers that 161 is divisible by are 1, 7, 23, and 161. You may also be interested to know that all the numbers that 161 is divisible by are also known as the factors of 161. In view of this, is 161 a prime number?

## Is 161 an odd number?

Yes, 161 is a deficient number, that is to say 161 is a natural number that is strictly larger than the sum of its proper divisors, i.e., the divisors of 161 without 161 itself (that is 1 + 7 + 23 = 31 ). 161 is an odd number, because it is not evenly divisible by 2. What is an even number?

**What is the prime factorization of 161?**

To be 161 a prime number, it would have been required that 161 has only two divisors, i.e., itself and 1. However, 161 is a semiprime (also called biprime or 2 -almost-prime), because it is the product of a two non-necessarily distinct prime numbers. Indeed, 161 = 7 x 23, where 7 and 23 are both prime numbers.

### Is 161 a semiprime?

However, 161 is a semiprime (also called biprime or 2 -almost-prime), because it is the product of a two non-necessarily distinct prime numbers. Indeed, 161 = 7 x 23, where 7 and 23 are both prime numbers.
