Answers
Step-by-step explanation:
Here are the first several prime factors: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29...
Let's start by dividing 316 by 2
316 ÷ 2 = 158 - No remainder! 2 is one of the factors!
158 ÷ 2 = 79 - No remainder! 2 is one of the factors!
79 ÷ 2 = 39.5 - There is a remainder. We can't divide by 2 evenly anymore. Let's try the next prime number
79 ÷ 3 = 26.3333 - This has a remainder. 3 is not a factor.
79 ÷ 5 = 15.8 - This has a remainder. 5 is not a factor.
79 ÷ 7 = 11.2857 - This has a remainder. 7 is not a factor.
...
Keep trying increasingly larger numbers until you find one that divides evenly.
...
79 ÷ 79 = 1 - No remainder! 79 is one of the factors!
The orange divisor(s) above are the prime factors of the number 316. If we put all of it together we have the factors 2 x 2 x 79 = 316. It can also be written in exponential form as 22 x 791.
