Is 62 a prime number?
62 is not a prime number. Here is the quickest way to see it.
The answer
No. 62 is not a prime number: 2 × 31 = 62.
How to see that 62 is not prime
62 is even, and every even number can be divided by 2, so 2 is a factor as well as 1 and 62.
62 has four factors: 1 and 62, plus one pair in between, 2 and 31.
Split 62 into prime factors
62 splits straight into two primes, 2 × 31, so its factor tree has only one branch.
62 in the times tables
No fact from the 2 to 12 times tables, up to × 12, makes 62. Its smallest pair, 2 × 31, needs the 31 times table, which goes past 12.
