Given numbers are 721, 819, 425, 272

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

Apply this formula for all numbers.

Step1:

LCM(721, 819) = 84357

GCD(721, 819) = ( 721 x 819 ) / 84357

= 721 / 819

= 721

Step2:

LCM(7, 425) = 2975

GCD(7, 425) = ( 7 x 425 ) / 2975

= 7 / 425

= 7

Step3:

LCM(1, 272) = 272

GCD(1, 272) = ( 1 x 272 ) / 272

= 1 / 272

= 1

So, Greatest Common Divisor of 721, 819, 425, 272 is 1
