Given numbers are 687, 121, 915, 932

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

Apply this formula for all numbers.

Step1:

LCM(687, 121) = 83127

GCD(687, 121) = ( 687 x 121 ) / 83127

= 687 / 121

= 687

Step2:

LCM(1, 915) = 915

GCD(1, 915) = ( 1 x 915 ) / 915

= 1 / 915

= 1

Step3:

LCM(1, 932) = 932

GCD(1, 932) = ( 1 x 932 ) / 932

= 1 / 932

= 1

So, Greatest Common Divisor of 687, 121, 915, 932 is 1
