Given numbers are 647, 479, 568, 839

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

Apply this formula for all numbers.

Step1:

LCM(647, 479) = 309913

GCD(647, 479) = ( 647 x 479 ) / 309913

= 647 / 479

= 647

Step2:

LCM(1, 568) = 568

GCD(1, 568) = ( 1 x 568 ) / 568

= 1 / 568

= 1

Step3:

LCM(1, 839) = 839

GCD(1, 839) = ( 1 x 839 ) / 839

= 1 / 839

= 1

So, Greatest Common Divisor of 647, 479, 568, 839 is 1
