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)
