Given numbers are 815, 142, 676, 764

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 142 are 2 x 71

Prime factors of 676 are 2 x 2 x 13 x 13

Prime factors of 764 are 2 x 2 x 191

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

Given numbers are 815, 142, 676, 764

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

Apply this formula for all numbers.

Step1:

LCM(815, 142) = 115730

GCD(815, 142) = ( 815 x 142 ) / 115730

= 815 / 142

= 815

Step2:

LCM(1, 676) = 676

GCD(1, 676) = ( 1 x 676 ) / 676

= 1 / 676

= 1

Step3:

LCM(1, 764) = 764

GCD(1, 764) = ( 1 x 764 ) / 764

= 1 / 764

= 1

So, Greatest Common Divisor of 815, 142, 676, 764 is 1
