To find the numbers, you can start with any factor pair of the number and keep factoring the composite numbers until all factors are prime. 315 3 x 105 3 x 3 x 35 3 x 3 x 5 x 7 = 315
5 minus 63 = -58 5 times 63 = 315

Multiply them.3 x 3 x 5 x 7 = 315

The first step is to express these numbers as products of their prime factors: 315 = 3x3x5x7 660 = 2x2x3x5x11 The next step is to identify any common prime factors. In this case the common prime factors are 3 and 5. Multiply these and you get: 3x5 = 15 Thus the HCF of 315 and 660 is 15.

No, 315 is not a prime number. It is called a composite number. A prime number is a number that is only divisible by one and itself. For example, the number 11 is a prime number since only 11 and 1 go into 11 evenly. 315 is divisible by other numbers (ex: it is divisible by 5)
