GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(789, 237) = 62331
GCD(789, 237) = ( 789 x 237 ) / 62331
= 789 / 237
= 789
Step2:
LCM(3, 520) = 1560
GCD(3, 520) = ( 3 x 520 ) / 1560
= 3 / 520
= 3
Step3:
LCM(1, 139) = 139
GCD(1, 139) = ( 1 x 139 ) / 139
= 1 / 139
= 1
So, Greatest Common Divisor of 789, 237, 520, 139 is 1
