(adsbygoogle = window.adsbygoogle || []).push({}); Yeah I need to know Asap.

The Prime Factors of 225 are - 3x3x5x5

Prime Factorization (Same thing) of 315 - 3x3x5x7

What is the HCM or GCM (Highest/Greatest Common Multiple)?

Since you already got the prime factors, get the ones that are common from both, in this case 3, 3, 5. Multiply all of them so your answer is 45.
