Given numbers are 870, 847, 912, 715

The list of prime factors of all numbers are

Prime factors of 870 are 2 x 3 x 5 x 29

Prime factors of 847 are 7 x 11 x 11

Prime factors of 912 are 2 x 2 x 2 x 2 x 3 x 19

Prime factors of 715 are 5 x 11 x 13

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 870, 847, 912, 715

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(870, 847) = 736890

GCD(870, 847) = ( 870 x 847 ) / 736890

= 870 / 847

= 870

Step2:

LCM(1, 912) = 912

GCD(1, 912) = ( 1 x 912 ) / 912

= 1 / 912

= 1

Step3:

LCM(1, 715) = 715

GCD(1, 715) = ( 1 x 715 ) / 715

= 1 / 715

= 1

So, Greatest Common Divisor of 870, 847, 912, 715 is 1
