Is 94 a prime number?
94 is not a prime number. Here is a way to check it.
The answer
No. 94 is not a prime number: 2 × 47 = 94.
How to see that 94 is not prime
94 is even, and every even number can be divided by 2, so 2 is a factor as well as 1 and 94.
94 has four factors: 1 and 94, plus one pair in between, 2 and 47.

94 splits straight into two primes, 2 × 47, so its factor tree has only one branch.
94 in the times tables
No fact from the 2 to 12 times tables, up to × 12, makes 94. Its smallest pair, 2 × 47, needs the 47 times table, which goes past 12.

94 backwards is 49. 49 is not prime. 49 is odd, its digits do not add up to a multiple of 3, and it does not end in 5, so the quick checks for 2, 3 and 5 all fail. Try 7 next: 7 × 7 = 49. Check 49 in full
