Given numbers are 647, 945, 475, 789

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

Apply this formula for all numbers.

Step1:

LCM(647, 945) = 611415

GCD(647, 945) = ( 647 x 945 ) / 611415

= 647 / 945

= 647

Step2:

LCM(1, 475) = 475

GCD(1, 475) = ( 1 x 475 ) / 475

= 1 / 475

= 1

Step3:

LCM(1, 789) = 789

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

= 1 / 789

= 1

So, Greatest Common Divisor of 647, 945, 475, 789 is 1
