Given numbers are 477, 792, 77, 647

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

Apply this formula for all numbers.

Step1:

LCM(477, 792) = 41976

GCD(477, 792) = ( 477 x 792 ) / 41976

= 477 / 792

= 477

Step2:

LCM(9, 77) = 693

GCD(9, 77) = ( 9 x 77 ) / 693

= 9 / 77

= 9

Step3:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

So, Greatest Common Divisor of 477, 792, 77, 647 is 1
