Given numbers are 687, 434, 474, 921

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

Apply this formula for all numbers.

Step1:

LCM(687, 434) = 298158

GCD(687, 434) = ( 687 x 434 ) / 298158

= 687 / 434

= 687

Step2:

LCM(1, 474) = 474

GCD(1, 474) = ( 1 x 474 ) / 474

= 1 / 474

= 1

Step3:

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

= 1 / 921

= 1

So, Greatest Common Divisor of 687, 434, 474, 921 is 1
