GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 188) = 120132
GCD(639, 188) = ( 639 x 188 ) / 120132
= 639 / 188
= 639
Step2:
LCM(1, 985) = 985
GCD(1, 985) = ( 1 x 985 ) / 985
= 1 / 985
= 1
Step3:
LCM(1, 417) = 417
GCD(1, 417) = ( 1 x 417 ) / 417
= 1 / 417
= 1
So, Greatest Common Divisor of 639, 188, 985, 417 is 1
