Is 95 a prime number?
95 is not a prime number. Here is the quickest way to see it.
The answer
No. 95 is not a prime number: 5 × 19 = 95.
How to see that 95 is not prime
95 ends in 5, and every number ending in 5 or 0 is in the 5 times table, so 5 is a factor.
95 has four factors: 1 and 95, plus one pair in between, 5 and 19.
Split 95 into prime factors
95 splits straight into two primes, 5 × 19, so its factor tree has only one branch.
95 in the times tables
No fact from the 2 to 12 times tables, up to × 12, makes 95. Its smallest pair, 5 × 19, needs the 19 times table, which goes past 12.
See the 19 times table, where 19 × 5 = 95 is one of the facts.
