Given numbers are 687, 327, 395, 660
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 327) = 74883
GCD(687, 327) = ( 687 x 327 ) / 74883
= 687 / 327
= 687
Step2:
LCM(3, 395) = 1185
GCD(3, 395) = ( 3 x 395 ) / 1185
= 3 / 395
= 3
Step3:
LCM(1, 660) = 660
GCD(1, 660) = ( 1 x 660 ) / 660
= 1 / 660
= 1
So, Greatest Common Divisor of 687, 327, 395, 660 is 1
