Given numbers are 221, 786, 451

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

Apply this formula for all numbers.

Step1:

LCM(221, 786) = 173706

GCD(221, 786) = ( 221 x 786 ) / 173706

= 221 / 786

= 221

Step2:

LCM(1, 451) = 451

GCD(1, 451) = ( 1 x 451 ) / 451

= 1 / 451

= 1

So, Greatest Common Divisor of 221, 786, 451 is 1
