Given numbers are 813, 265, 212, 221

The list of prime factors of all numbers are

Prime factors of 813 are 3 x 271

Prime factors of 265 are 5 x 53

Prime factors of 212 are 2 x 2 x 53

Prime factors of 221 are 13 x 17

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 813, 265, 212, 221

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

Apply this formula for all numbers.

Step1:

LCM(813, 265) = 215445

GCD(813, 265) = ( 813 x 265 ) / 215445

= 813 / 265

= 813

Step2:

LCM(1, 212) = 212

GCD(1, 212) = ( 1 x 212 ) / 212

= 1 / 212

= 1

Step3:

LCM(1, 221) = 221

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

= 1 / 221

= 1

So, Greatest Common Divisor of 813, 265, 212, 221 is 1
