Given numbers are 645, 746, 818, 211
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 746) = 481170
GCD(645, 746) = ( 645 x 746 ) / 481170
= 645 / 746
= 645
Step2:
LCM(1, 818) = 818
GCD(1, 818) = ( 1 x 818 ) / 818
= 1 / 818
= 1
Step3:
LCM(1, 211) = 211
GCD(1, 211) = ( 1 x 211 ) / 211
= 1 / 211
= 1
So, Greatest Common Divisor of 645, 746, 818, 211 is 1
