Given numbers are 221, 606, 655

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

Apply this formula for all numbers.

Step1:

LCM(221, 606) = 133926

GCD(221, 606) = ( 221 x 606 ) / 133926

= 221 / 606

= 221

Step2:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

So, Greatest Common Divisor of 221, 606, 655 is 1
