2*2*19=76.
1 IS NOT A PRIME NUMBER.
(In mathematics, a prime number (or a prime) is a natural number that has exactly two (distinct) natural number divisors, which are 1 and the prime number itself. There exists an infinitude of prime numbers, as demonstrated by Euclid in about 300 B.C.. The first 30 prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101, 103, 107, 109, and 113 )

76 = 2 x 2 x 19. 1 is not a prime number. 19 is a prime number.

What extra 1? And if you divided 76 by 4, what was the result? Was that a prime. What are the prime factors of 4?

To get the prime factors (thats what you want here) of any number, just start by dividing the number by 2 as many times as it will go, then 3, etc. For example, find the factors of 780
780 / 2 = 390
390 / 2 = 195
195 / 2 --- doesnt go.
195 / 3 = 65
65 / 3 --- doesn't go
65 /4 --- doesn't go
65/5 = 13
13 / 6 -- doesn't go, etc.
13 / 13 = 1
The factors are 2*2*3*5*13

76 = 2 * 2 * 19 = 2^2 * 19

2*2*2*2*2*2. These are 2 raises to the power of 6.
