Given numbers are 647, 659, 227, 720

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

Apply this formula for all numbers.

Step1:

LCM(647, 659) = 426373

GCD(647, 659) = ( 647 x 659 ) / 426373

= 647 / 659

= 647

Step2:

LCM(1, 227) = 227

GCD(1, 227) = ( 1 x 227 ) / 227

= 1 / 227

= 1

Step3:

LCM(1, 720) = 720

GCD(1, 720) = ( 1 x 720 ) / 720

= 1 / 720

= 1

So, Greatest Common Divisor of 647, 659, 227, 720 is 1
