Given numbers are 822, 164, 663, 221

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

Apply this formula for all numbers.

Step1:

LCM(822, 164) = 67404

GCD(822, 164) = ( 822 x 164 ) / 67404

= 822 / 164

= 822

Step2:

LCM(2, 663) = 1326

GCD(2, 663) = ( 2 x 663 ) / 1326

= 2 / 663

= 2

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 822, 164, 663, 221 is 1
