Given numbers are 908, 644, 747, 789

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

Apply this formula for all numbers.

Step1:

LCM(908, 644) = 146188

GCD(908, 644) = ( 908 x 644 ) / 146188

= 908 / 644

= 908

Step2:

LCM(4, 747) = 2988

GCD(4, 747) = ( 4 x 747 ) / 2988

= 4 / 747

= 4

Step3:

LCM(1, 789) = 789

GCD(1, 789) = ( 1 x 789 ) / 789

= 1 / 789

= 1

So, Greatest Common Divisor of 908, 644, 747, 789 is 1
