Is sixty-one a prime number?
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.

What is the product of three prime numbers?
Obviously, the answer is a composite number. Reason:A number multiplied by another number (besides 1) will give a result of a composite number. If a number is multiplied by 0, the answer will be 0 (which is not a prime number nor composite) unless a number has been added or subtracted to give either a negative or positive number, respectively.

How are these extremely large prime numbers found?
There is no formula that will specifically give you a prime number and no non-prime number. Therefore, several large numbers are tested to see if they are primes, until a prime number is found.
