GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(261, 168) = 14616
GCD(261, 168) = ( 261 x 168 ) / 14616
= 261 / 168
= 261
Step2:
LCM(3, 378) = 378
GCD(3, 378) = ( 3 x 378 ) / 378
= 3 / 378
= 3
Step3:
LCM(3, 627) = 627
GCD(3, 627) = ( 3 x 627 ) / 627
= 3 / 627
= 3
So, Greatest Common Divisor of 261, 168, 378, 627 is 3
