Given numbers are 815, 606, 77, 615

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 606 are 2 x 3 x 101

Prime factors of 77 are 7 x 11

Prime factors of 615 are 3 x 5 x 41

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

Given numbers are 815, 606, 77, 615

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

Apply this formula for all numbers.

Step1:

LCM(815, 606) = 493890

GCD(815, 606) = ( 815 x 606 ) / 493890

= 815 / 606

= 815

Step2:

LCM(1, 77) = 77

GCD(1, 77) = ( 1 x 77 ) / 77

= 1 / 77

= 1

Step3:

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

= 1 / 615

= 1

So, Greatest Common Divisor of 815, 606, 77, 615 is 1
