Given numbers are 221, 604, 721, 798

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

Apply this formula for all numbers.

Step1:

LCM(221, 604) = 133484

GCD(221, 604) = ( 221 x 604 ) / 133484

= 221 / 604

= 221

Step2:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

Step3:

LCM(1, 798) = 798

GCD(1, 798) = ( 1 x 798 ) / 798

= 1 / 798

= 1

So, Greatest Common Divisor of 221, 604, 721, 798 is 1
