Given numbers are 955, 635, 821, 687

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

Apply this formula for all numbers.

Step1:

LCM(955, 635) = 121285

GCD(955, 635) = ( 955 x 635 ) / 121285

= 955 / 635

= 955

Step2:

LCM(5, 821) = 4105

GCD(5, 821) = ( 5 x 821 ) / 4105

= 5 / 821

= 5

Step3:

LCM(1, 687) = 687

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

= 1 / 687

= 1

So, Greatest Common Divisor of 955, 635, 821, 687 is 1
