Given numbers are 789, 492, 643, 777

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(789, 492) = 129396

GCD(789, 492) = ( 789 x 492 ) / 129396

= 789 / 492

= 789

Step2:

LCM(3, 643) = 1929

GCD(3, 643) = ( 3 x 643 ) / 1929

= 3 / 643

= 3

Step3:

LCM(1, 777) = 777

GCD(1, 777) = ( 1 x 777 ) / 777

= 1 / 777

= 1

So, Greatest Common Divisor of 789, 492, 643, 777 is 1
