Given numbers are 662, 221, 658, 817

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

Apply this formula for all numbers.

Step1:

LCM(662, 221) = 146302

GCD(662, 221) = ( 662 x 221 ) / 146302

= 662 / 221

= 662

Step2:

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

= 1 / 658

= 1

Step3:

LCM(1, 817) = 817

GCD(1, 817) = ( 1 x 817 ) / 817

= 1 / 817

= 1

So, Greatest Common Divisor of 662, 221, 658, 817 is 1
