GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 774) = 3870
GCD(645, 774) = ( 645 x 774 ) / 3870
= 645 / 774
= 645
Step2:
LCM(129, 447) = 19221
GCD(129, 447) = ( 129 x 447 ) / 19221
= 129 / 447
= 129
Step3:
LCM(3, 888) = 888
GCD(3, 888) = ( 3 x 888 ) / 888
= 3 / 888
= 3
So, Greatest Common Divisor of 645, 774, 447, 888 is 3
