A*B*C = 135
A + B + C = 17
First find the factors of 135.
135 = 3 * 3 * 3 * 5
Work out how many different ways there are to multiply 3 numbers from these 4 factors.
Do this now before you read the next line.
You can make 3 * 3 * 15 or 3 * 9 * 5 and that's all !
But for the first one, the numbers sum to 3 + 3 + 15 = 21, whereas, for the second one, 3 + 9 + 5 = 17, which is what we want.
Therefore, the numbers are 3, 5 and 9.
