Given numbers are 789, 640, 918, 347

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

Apply this formula for all numbers.

Step1:

LCM(789, 640) = 504960

GCD(789, 640) = ( 789 x 640 ) / 504960

= 789 / 640

= 789

Step2:

LCM(1, 918) = 918

GCD(1, 918) = ( 1 x 918 ) / 918

= 1 / 918

= 1

Step3:

LCM(1, 347) = 347

GCD(1, 347) = ( 1 x 347 ) / 347

= 1 / 347

= 1

So, Greatest Common Divisor of 789, 640, 918, 347 is 1
