The greatest common factor (GCF, not GFC) of 315, 105 and 21 can be calculated by writing down each number's factors. The factorization for the given numbers is: 315 = 3 x 3 x 5 x 7 105 = 3 x 5 x 7 21 = 3 x 7 The common factors are 3 x 7 = 21, so the GCF of 315, 105 and 21 is 21.
315
Oh, what a happy little question! Let's break down 630 into its prime factors. We start by dividing it by 2 to get 315, then by 3 to get 105, then by 3 again to get 35, and finally by 5 to get 7. So, the prime factors of 630 are 2 x 3 x 3 x 5 x 7.
32*5*7 = 315
32 x 5 x 7 = 315
315 = 3 * 3 * 5 * 7 This can also be written using exponents as: 32 * 5 * 7
3 x 3 x 5 x 7 = 315
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) .
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.
315 = 3 x 3 x 5 x 7
3 x 3 x 5 x 7 = 315
