Given numbers are 639, 141, 990, 238
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 141) = 30033
GCD(639, 141) = ( 639 x 141 ) / 30033
= 639 / 141
= 639
Step2:
LCM(3, 990) = 990
GCD(3, 990) = ( 3 x 990 ) / 990
= 3 / 990
= 3
Step3:
LCM(3, 238) = 714
GCD(3, 238) = ( 3 x 238 ) / 714
= 3 / 238
= 3
So, Greatest Common Divisor of 639, 141, 990, 238 is 1
