Given numbers are 815, 656, 160, 620

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 656 are 2 x 2 x 2 x 2 x 41

Prime factors of 160 are 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 620 are 2 x 2 x 5 x 31

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

Given numbers are 815, 656, 160, 620

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

Apply this formula for all numbers.

Step1:

LCM(815, 656) = 534640

GCD(815, 656) = ( 815 x 656 ) / 534640

= 815 / 656

= 815

Step2:

LCM(1, 160) = 160

GCD(1, 160) = ( 1 x 160 ) / 160

= 1 / 160

= 1

Step3:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 815, 656, 160, 620 is 1
