Given numbers are 405, 873, 840, 151

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 873 are 3 x 3 x 97

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 151 are 151

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

Given numbers are 405, 873, 840, 151

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

Apply this formula for all numbers.

Step1:

LCM(405, 873) = 39285

GCD(405, 873) = ( 405 x 873 ) / 39285

= 405 / 873

= 405

Step2:

LCM(9, 840) = 2520

GCD(9, 840) = ( 9 x 840 ) / 2520

= 9 / 840

= 9

Step3:

LCM(3, 151) = 453

GCD(3, 151) = ( 3 x 151 ) / 453

= 3 / 151

= 3

So, Greatest Common Divisor of 405, 873, 840, 151 is 1
