Given numbers are 515, 697, 696, 870

The list of prime factors of all numbers are

Prime factors of 515 are 5 x 103

Prime factors of 697 are 17 x 41

Prime factors of 696 are 2 x 2 x 2 x 3 x 29

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

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

Given numbers are 515, 697, 696, 870

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

Apply this formula for all numbers.

Step1:

LCM(515, 697) = 358955

GCD(515, 697) = ( 515 x 697 ) / 358955

= 515 / 697

= 515

Step2:

LCM(1, 696) = 696

GCD(1, 696) = ( 1 x 696 ) / 696

= 1 / 696

= 1

Step3:

LCM(1, 870) = 870

GCD(1, 870) = ( 1 x 870 ) / 870

= 1 / 870

= 1

So, Greatest Common Divisor of 515, 697, 696, 870 is 1
