Given numbers are 687, 353, 991, 579

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

Apply this formula for all numbers.

Step1:

LCM(687, 353) = 242511

GCD(687, 353) = ( 687 x 353 ) / 242511

= 687 / 353

= 687

Step2:

LCM(1, 991) = 991

GCD(1, 991) = ( 1 x 991 ) / 991

= 1 / 991

= 1

Step3:

LCM(1, 579) = 579

GCD(1, 579) = ( 1 x 579 ) / 579

= 1 / 579

= 1

So, Greatest Common Divisor of 687, 353, 991, 579 is 1
