GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 982) = 627498
GCD(639, 982) = ( 639 x 982 ) / 627498
= 639 / 982
= 639
Step2:
LCM(1, 237) = 237
GCD(1, 237) = ( 1 x 237 ) / 237
= 1 / 237
= 1
Step3:
LCM(1, 768) = 768
GCD(1, 768) = ( 1 x 768 ) / 768
= 1 / 768
= 1
So, Greatest Common Divisor of 639, 982, 237, 768 is 1
