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

Apply this formula for all numbers.

Step1:

LCM(687, 372) = 85188

GCD(687, 372) = ( 687 x 372 ) / 85188

= 687 / 372

= 687

Step2:

LCM(3, 988) = 2964

GCD(3, 988) = ( 3 x 988 ) / 2964

= 3 / 988

= 3

Step3:

LCM(1, 243) = 243

GCD(1, 243) = ( 1 x 243 ) / 243

= 1 / 243

= 1

So, Greatest Common Divisor of 687, 372, 988, 243 is 1
