Given numbers are 637, 135, 168, 831

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

Apply this formula for all numbers.

Step1:

LCM(637, 135) = 85995

GCD(637, 135) = ( 637 x 135 ) / 85995

= 637 / 135

= 637

Step2:

LCM(1, 168) = 168

GCD(1, 168) = ( 1 x 168 ) / 168

= 1 / 168

= 1

Step3:

LCM(1, 831) = 831

GCD(1, 831) = ( 1 x 831 ) / 831

= 1 / 831

= 1

So, Greatest Common Divisor of 637, 135, 168, 831 is 1
