GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 989) = 660652
GCD(668, 989) = ( 668 x 989 ) / 660652
= 668 / 989
= 668
Step2:
LCM(1, 198) = 198
GCD(1, 198) = ( 1 x 198 ) / 198
= 1 / 198
= 1
Step3:
LCM(1, 623) = 623
GCD(1, 623) = ( 1 x 623 ) / 623
= 1 / 623
= 1
So, Greatest Common Divisor of 668, 989, 198, 623 is 1
