GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(789, 655) = 516795
GCD(789, 655) = ( 789 x 655 ) / 516795
= 789 / 655
= 789
Step2:
LCM(1, 323) = 323
GCD(1, 323) = ( 1 x 323 ) / 323
= 1 / 323
= 1
Step3:
LCM(1, 219) = 219
GCD(1, 219) = ( 1 x 219 ) / 219
= 1 / 219
= 1
So, Greatest Common Divisor of 789, 655, 323, 219 is 1
