Given numbers are 687, 764, 239, 928

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

Apply this formula for all numbers.

Step1:

LCM(687, 764) = 524868

GCD(687, 764) = ( 687 x 764 ) / 524868

= 687 / 764

= 687

Step2:

LCM(1, 239) = 239

GCD(1, 239) = ( 1 x 239 ) / 239

= 1 / 239

= 1

Step3:

LCM(1, 928) = 928

GCD(1, 928) = ( 1 x 928 ) / 928

= 1 / 928

= 1

So, Greatest Common Divisor of 687, 764, 239, 928 is 1
