Given numbers are 458, 670, 221

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

Apply this formula for all numbers.

Step1:

LCM(458, 670) = 153430

GCD(458, 670) = ( 458 x 670 ) / 153430

= 458 / 670

= 458

Step2:

LCM(2, 221) = 442

GCD(2, 221) = ( 2 x 221 ) / 442

= 2 / 221

= 2

So, Greatest Common Divisor of 458, 670, 221 is 1
