Given numbers are 687, 657, 279, 919

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

Apply this formula for all numbers.

Step1:

LCM(687, 657) = 150453

GCD(687, 657) = ( 687 x 657 ) / 150453

= 687 / 657

= 687

Step2:

LCM(3, 279) = 279

GCD(3, 279) = ( 3 x 279 ) / 279

= 3 / 279

= 3

Step3:

LCM(3, 919) = 2757

GCD(3, 919) = ( 3 x 919 ) / 2757

= 3 / 919

= 3

So, Greatest Common Divisor of 687, 657, 279, 919 is 1
