Given numbers are 221, 353, 436, 851

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

Apply this formula for all numbers.

Step1:

LCM(221, 353) = 78013

GCD(221, 353) = ( 221 x 353 ) / 78013

= 221 / 353

= 221

Step2:

LCM(1, 436) = 436

GCD(1, 436) = ( 1 x 436 ) / 436

= 1 / 436

= 1

Step3:

LCM(1, 851) = 851

GCD(1, 851) = ( 1 x 851 ) / 851

= 1 / 851

= 1

So, Greatest Common Divisor of 221, 353, 436, 851 is 1
