A Prime number is one which cannot be evenly divided by any prime number
61 ÷ 2 = 30 +1
61 ÷ 3 = 20 +1
61 ÷ 5 = 12 +1
61 ÷ 7 = 8 + 5
As the square root of 61 lies between 7 and 8, there is no need to take the division further than this... any prime number which might have divided it would give a result lower than the number we have already tried.
So, yes! 61 is a prime number.

A prime number times a prime number is a composite number. Since prime numbers, except for 2, are odd numbers, a prime number times a prime number is usually an odd number. It will only be an even number if one of the prime numbers is 2. A prime number times a prime number will be a number with four factors unless both prime numbers are the same, in which case it will be a square number with only three factors.
