Given numbers are 312, 715, 665, 797

The list of prime factors of all numbers are

Prime factors of 312 are 2 x 2 x 2 x 3 x 13

Prime factors of 715 are 5 x 11 x 13

Prime factors of 665 are 5 x 7 x 19

Prime factors of 797 are 797

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

Given numbers are 312, 715, 665, 797

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

Apply this formula for all numbers.

Step1:

LCM(312, 715) = 17160

GCD(312, 715) = ( 312 x 715 ) / 17160

= 312 / 715

= 312

Step2:

LCM(13, 665) = 8645

GCD(13, 665) = ( 13 x 665 ) / 8645

= 13 / 665

= 13

Step3:

LCM(1, 797) = 797

GCD(1, 797) = ( 1 x 797 ) / 797

= 1 / 797

= 1

So, Greatest Common Divisor of 312, 715, 665, 797 is 1
