Given numbers are 870, 522, 764, 515

The list of prime factors of all numbers are

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

Prime factors of 522 are 2 x 3 x 3 x 29

Prime factors of 764 are 2 x 2 x 191

Prime factors of 515 are 5 x 103

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

Given numbers are 870, 522, 764, 515

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

Apply this formula for all numbers.

Step1:

LCM(870, 522) = 2610

GCD(870, 522) = ( 870 x 522 ) / 2610

= 870 / 522

= 870

Step2:

LCM(174, 764) = 66468

GCD(174, 764) = ( 174 x 764 ) / 66468

= 174 / 764

= 174

Step3:

LCM(2, 515) = 1030

GCD(2, 515) = ( 2 x 515 ) / 1030

= 2 / 515

= 2

So, Greatest Common Divisor of 870, 522, 764, 515 is 1
