GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 879) = 188985
GCD(645, 879) = ( 645 x 879 ) / 188985
= 645 / 879
= 645
Step2:
LCM(3, 311) = 933
GCD(3, 311) = ( 3 x 311 ) / 933
= 3 / 311
= 3
Step3:
LCM(1, 949) = 949
GCD(1, 949) = ( 1 x 949 ) / 949
= 1 / 949
= 1
So, Greatest Common Divisor of 645, 879, 311, 949 is 1
