GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(792, 420) = 27720
GCD(792, 420) = ( 792 x 420 ) / 27720
= 792 / 420
= 792
Step2:
LCM(12, 387) = 1548
GCD(12, 387) = ( 12 x 387 ) / 1548
= 12 / 387
= 12
Step3:
LCM(3, 789) = 789
GCD(3, 789) = ( 3 x 789 ) / 789
= 3 / 789
= 3
So, Greatest Common Divisor of 792, 420, 387, 789 is 3
