GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(789, 141) = 37083
GCD(789, 141) = ( 789 x 141 ) / 37083
= 789 / 141
= 789
Step2:
LCM(3, 639) = 639
GCD(3, 639) = ( 3 x 639 ) / 639
= 3 / 639
= 3
Step3:
LCM(3, 439) = 1317
GCD(3, 439) = ( 3 x 439 ) / 1317
= 3 / 439
= 3
So, Greatest Common Divisor of 789, 141, 639, 439 is 1
