Given numbers are 821, 221, 650

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

Apply this formula for all numbers.

Step1:

LCM(821, 221) = 181441

GCD(821, 221) = ( 821 x 221 ) / 181441

= 821 / 221

= 821

Step2:

LCM(1, 650) = 650

GCD(1, 650) = ( 1 x 650 ) / 650

= 1 / 650

= 1

So, Greatest Common Divisor of 821, 221, 650 is 1
