Given numbers are 812, 221, 911, 199

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

Apply this formula for all numbers.

Step1:

LCM(812, 221) = 179452

GCD(812, 221) = ( 812 x 221 ) / 179452

= 812 / 221

= 812

Step2:

LCM(1, 911) = 911

GCD(1, 911) = ( 1 x 911 ) / 911

= 1 / 911

= 1

Step3:

LCM(1, 199) = 199

GCD(1, 199) = ( 1 x 199 ) / 199

= 1 / 199

= 1

So, Greatest Common Divisor of 812, 221, 911, 199 is 1
