Given numbers are 819, 129, 974, 687

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

Apply this formula for all numbers.

Step1:

LCM(819, 129) = 35217

GCD(819, 129) = ( 819 x 129 ) / 35217

= 819 / 129

= 819

Step2:

LCM(3, 974) = 2922

GCD(3, 974) = ( 3 x 974 ) / 2922

= 3 / 974

= 3

Step3:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

So, Greatest Common Divisor of 819, 129, 974, 687 is 1
