Given numbers are 187, 687, 121
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(187, 687) = 128469
GCD(187, 687) = ( 187 x 687 ) / 128469
= 187 / 687
= 187
Step2:
LCM(1, 121) = 121
GCD(1, 121) = ( 1 x 121 ) / 121
= 1 / 121
= 1
So, Greatest Common Divisor of 187, 687, 121 is 1
