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

Given numbers are 657, 221, 815, 576

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

Apply this formula for all numbers.

Step1:

LCM(657, 221) = 145197

GCD(657, 221) = ( 657 x 221 ) / 145197

= 657 / 221

= 657

Step2:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

Step3:

LCM(1, 576) = 576

GCD(1, 576) = ( 1 x 576 ) / 576

= 1 / 576

= 1

So, Greatest Common Divisor of 657, 221, 815, 576 is 1
