Given numbers are 405, 141, 353, 771

The list of prime factors of all numbers are

Prime factors of 405 are 3 x 3 x 3 x 3 x 5

Prime factors of 141 are 3 x 47

Prime factors of 353 are 353

Prime factors of 771 are 3 x 257

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

Given numbers are 405, 141, 353, 771

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

Apply this formula for all numbers.

Step1:

LCM(405, 141) = 19035

GCD(405, 141) = ( 405 x 141 ) / 19035

= 405 / 141

= 405

Step2:

LCM(3, 353) = 1059

GCD(3, 353) = ( 3 x 353 ) / 1059

= 3 / 353

= 3

Step3:

LCM(1, 771) = 771

GCD(1, 771) = ( 1 x 771 ) / 771

= 1 / 771

= 1

So, Greatest Common Divisor of 405, 141, 353, 771 is 1
