3 x 3 x 5 x 7 = 315
3 x 3 x 5 x 7 = 315 2 x 3 x 3 x 5 x 5 = 450
Since '315' ends in '5', a prime number, we can start there. Hence dividing by '5' , and then keep on divising by prime numbers. 5)315 3)63 3)21 7)7 = 1 Always reduce to '1' The factoprs of 315 are 3,3,5,&7. In exponent form 3^(2) X 5^(1) x 7^(1) .
315 = 3 * 3 * 5 * 7 This can also be written using exponents as: 32 * 5 * 7
Steps to find out LCM of two numbers(a & b):1- Find HCF of a & b.2- Multiply a and b.3- Divide the result of step 2 by HCF. The result is LCM.1- In order to find out HCF of 540 and 315 we shall use the method of prime factorization.Prime factorization of 540 = 2x2x3x3x3x5Prime factorization of 315 = 3x3x5x7HCF(540, 315) = 3x3x5 = 45.2- Product of 540 and 315.540 x 315 = 170100.3- LCM(540, 315) = 170100/45 = 3780.
3 x 3 x 5 x 7 = 315
32*5*7 = 315

32 x 5 x 7 = 315
3 x 3 x 5 x 7 = 315
3 x 3 x 5 x 7 = 315
3 x 3 x 5 x 7 = 315
The GCF of 36 and 315 is XXThe prime factorization of 36 is 2*2*3*3The prime factorization of 315 is 3*3*5*7Thus the GCF of 36 and 315 is 9.
280 x 315 = 88200 280% x 315 = 882
315 = 3 x 3 x 5 x 7
3 x 3 x 5 x 7 = 315
