How to Determine if a Number is Prime | Prime or Composite? 83 and 77 | Minute Math

In this video we learn how to determine if a number is prime. We determine if the numbers 83 and 77 are prime or composite.

The steps for determining if a number is prime are as follows:
1. Test each of the primes, in order, to see if it is a factor of the number.
2. Start with 2 and stop when the quotient is smaller than the divisor or when a prime factor is found.
3. If the number has a prime factor, then it is a composite number. If it has no prime factors, then the number is prime.
