Given numbers are 221, 987, 426

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

Apply this formula for all numbers.

Step1:

LCM(221, 987) = 218127

GCD(221, 987) = ( 221 x 987 ) / 218127

= 221 / 987

= 221

Step2:

LCM(1, 426) = 426

GCD(1, 426) = ( 1 x 426 ) / 426

= 1 / 426

= 1

So, Greatest Common Divisor of 221, 987, 426 is 1
