Given numbers are 441, 272, 390, 813

The list of prime factors of all numbers are

Prime factors of 441 are 3 x 3 x 7 x 7

Prime factors of 272 are 2 x 2 x 2 x 2 x 17

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 813 are 3 x 271

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

Given numbers are 441, 272, 390, 813

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

Apply this formula for all numbers.

Step1:

LCM(441, 272) = 119952

GCD(441, 272) = ( 441 x 272 ) / 119952

= 441 / 272

= 441

Step2:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

Step3:

LCM(1, 813) = 813

GCD(1, 813) = ( 1 x 813 ) / 813

= 1 / 813

= 1

So, Greatest Common Divisor of 441, 272, 390, 813 is 1
