Given numbers are 221, 731, 83, 256

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

Apply this formula for all numbers.

Step1:

LCM(221, 731) = 9503

GCD(221, 731) = ( 221 x 731 ) / 9503

= 221 / 731

= 221

Step2:

LCM(17, 83) = 1411

GCD(17, 83) = ( 17 x 83 ) / 1411

= 17 / 83

= 17

Step3:

LCM(1, 256) = 256

GCD(1, 256) = ( 1 x 256 ) / 256

= 1 / 256

= 1

So, Greatest Common Divisor of 221, 731, 83, 256 is 1
