Given numbers are 405, 605, 612, 140

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 605 are 5 x 11 x 11

Prime factors of 612 are 2 x 2 x 3 x 3 x 17

Prime factors of 140 are 2 x 2 x 5 x 7

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

Given numbers are 405, 605, 612, 140

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

Apply this formula for all numbers.

Step1:

LCM(405, 605) = 49005

GCD(405, 605) = ( 405 x 605 ) / 49005

= 405 / 605

= 405

Step2:

LCM(5, 612) = 3060

GCD(5, 612) = ( 5 x 612 ) / 3060

= 5 / 612

= 5

Step3:

LCM(1, 140) = 140

GCD(1, 140) = ( 1 x 140 ) / 140

= 1 / 140

= 1

So, Greatest Common Divisor of 405, 605, 612, 140 is 1
