Given numbers are 789, 437, 644

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

Apply this formula for all numbers.

Step1:

LCM(789, 437) = 344793

GCD(789, 437) = ( 789 x 437 ) / 344793

= 789 / 437

= 789

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 789, 437, 644 is 1
