Given numbers are 581, 397, 221, 111

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

Apply this formula for all numbers.

Step1:

LCM(581, 397) = 230657

GCD(581, 397) = ( 581 x 397 ) / 230657

= 581 / 397

= 581

Step2:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

Step3:

LCM(1, 111) = 111

GCD(1, 111) = ( 1 x 111 ) / 111

= 1 / 111

= 1

So, Greatest Common Divisor of 581, 397, 221, 111 is 1
