Given numbers are 647, 629, 809, 807

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

Apply this formula for all numbers.

Step1:

LCM(647, 629) = 406963

GCD(647, 629) = ( 647 x 629 ) / 406963

= 647 / 629

= 647

Step2:

LCM(1, 809) = 809

GCD(1, 809) = ( 1 x 809 ) / 809

= 1 / 809

= 1

Step3:

LCM(1, 807) = 807

GCD(1, 807) = ( 1 x 807 ) / 807

= 1 / 807

= 1

So, Greatest Common Divisor of 647, 629, 809, 807 is 1
