Given numbers are 815, 786, 764, 657

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 786 are 2 x 3 x 131

Prime factors of 764 are 2 x 2 x 191

Prime factors of 657 are 3 x 3 x 73

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

Given numbers are 815, 786, 764, 657

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

Apply this formula for all numbers.

Step1:

LCM(815, 786) = 640590

GCD(815, 786) = ( 815 x 786 ) / 640590

= 815 / 786

= 815

Step2:

LCM(1, 764) = 764

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

= 1 / 764

= 1

Step3:

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

= 1 / 657

= 1

So, Greatest Common Divisor of 815, 786, 764, 657 is 1
