Given numbers are 860, 424, 720, 647

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

Apply this formula for all numbers.

Step1:

LCM(860, 424) = 91160

GCD(860, 424) = ( 860 x 424 ) / 91160

= 860 / 424

= 860

Step2:

LCM(4, 720) = 720

GCD(4, 720) = ( 4 x 720 ) / 720

= 4 / 720

= 4

Step3:

LCM(4, 647) = 2588

GCD(4, 647) = ( 4 x 647 ) / 2588

= 4 / 647

= 4

So, Greatest Common Divisor of 860, 424, 720, 647 is 1
