Given numbers are 251, 345, 282, 405

The list of prime factors of all numbers are

Prime factors of 251 are 251

Prime factors of 345 are 3 x 5 x 23

Prime factors of 282 are 2 x 3 x 47

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

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

Given numbers are 251, 345, 282, 405

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

Apply this formula for all numbers.

Step1:

LCM(251, 345) = 86595

GCD(251, 345) = ( 251 x 345 ) / 86595

= 251 / 345

= 251

Step2:

LCM(1, 282) = 282

GCD(1, 282) = ( 1 x 282 ) / 282

= 1 / 282

= 1

Step3:

LCM(1, 405) = 405

GCD(1, 405) = ( 1 x 405 ) / 405

= 1 / 405

= 1

So, Greatest Common Divisor of 251, 345, 282, 405 is 1
