GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 381) = 81915
GCD(645, 381) = ( 645 x 381 ) / 81915
= 645 / 381
= 645
Step2:
LCM(3, 872) = 2616
GCD(3, 872) = ( 3 x 872 ) / 2616
= 3 / 872
= 3
Step3:
LCM(1, 632) = 632
GCD(1, 632) = ( 1 x 632 ) / 632
= 1 / 632
= 1
So, Greatest Common Divisor of 645, 381, 872, 632 is 1
