What are the prime factors of 472?

Answer 1

It's an even number, so it contains a factor of 2.

486/2 = 243.

So 486 = 2 * 243

243 is odd so no more factors of 2.

Is 243 a multiple of 3? Yes. 243/3 = 81 (no remainder).

So 486 = 2 * 3 * 81

81 should look familiar: 9*9 = 81. And we know that 9 = 3*3

Putting it all together:

486 = 2 * 3 * 3 * 3 * 3 * 3

486 = 2 * 3^5

Prime factors are 2 (once) and 3 (five times)
