Given numbers are 405, 387, 627, 761

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 387 are 3 x 3 x 43

Prime factors of 627 are 3 x 11 x 19

Prime factors of 761 are 761

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

Given numbers are 405, 387, 627, 761

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

Apply this formula for all numbers.

Step1:

LCM(405, 387) = 17415

GCD(405, 387) = ( 405 x 387 ) / 17415

= 405 / 387

= 405

Step2:

LCM(9, 627) = 1881

GCD(9, 627) = ( 9 x 627 ) / 1881

= 9 / 627

= 9

Step3:

LCM(3, 761) = 2283

GCD(3, 761) = ( 3 x 761 ) / 2283

= 3 / 761

= 3

So, Greatest Common Divisor of 405, 387, 627, 761 is 1
