Given numbers are 221, 724, 266, 315

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

Apply this formula for all numbers.

Step1:

LCM(221, 724) = 160004

GCD(221, 724) = ( 221 x 724 ) / 160004

= 221 / 724

= 221

Step2:

LCM(1, 266) = 266

GCD(1, 266) = ( 1 x 266 ) / 266

= 1 / 266

= 1

Step3:

LCM(1, 315) = 315

GCD(1, 315) = ( 1 x 315 ) / 315

= 1 / 315

= 1

So, Greatest Common Divisor of 221, 724, 266, 315 is 1
