Given numbers are 647, 877, 772, 979

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

Apply this formula for all numbers.

Step1:

LCM(647, 877) = 567419

GCD(647, 877) = ( 647 x 877 ) / 567419

= 647 / 877

= 647

Step2:

LCM(1, 772) = 772

GCD(1, 772) = ( 1 x 772 ) / 772

= 1 / 772

= 1

Step3:

LCM(1, 979) = 979

GCD(1, 979) = ( 1 x 979 ) / 979

= 1 / 979

= 1

So, Greatest Common Divisor of 647, 877, 772, 979 is 1
