Given numbers are 789, 331, 459, 663
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(789, 331) = 261159
GCD(789, 331) = ( 789 x 331 ) / 261159
= 789 / 331
= 789
Step2:
LCM(1, 459) = 459
GCD(1, 459) = ( 1 x 459 ) / 459
= 1 / 459
= 1
Step3:
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
= 1 / 663
= 1
So, Greatest Common Divisor of 789, 331, 459, 663 is 1
