914 is not a prime number.

A prime number has only two positive divisors: 1 and itself.

For 914, the positive divisors are :

• 1 is a divisor of 914 : $914 / 1 = 914$
• 2 is a divisor of 914 : $914 / 2 = 457$
• 457 is a divisor of 914 : $914 / 457 = 2$
• 914 is a divisor of 914 : $914 / 914 = 1$

Since 914 is divisible by 2 and 457, it has divisors other than 1 and itself.

Therefore, 914 is not a prime number.
