Given numbers are 647, 123, 586, 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, 123) = 79581

GCD(647, 123) = ( 647 x 123 ) / 79581

= 647 / 123

= 647

Step2:

LCM(1, 586) = 586

GCD(1, 586) = ( 1 x 586 ) / 586

= 1 / 586

= 1

Step3:

LCM(1, 807) = 807

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

= 1 / 807

= 1

So, Greatest Common Divisor of 647, 123, 586, 807 is 1
