Given numbers are 405, 290, 100, 444

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 290 are 2 x 5 x 29

Prime factors of 100 are 2 x 2 x 5 x 5

Prime factors of 444 are 2 x 2 x 3 x 37

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

Given numbers are 405, 290, 100, 444

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

Apply this formula for all numbers.

Step1:

LCM(405, 290) = 23490

GCD(405, 290) = ( 405 x 290 ) / 23490

= 405 / 290

= 405

Step2:

LCM(5, 100) = 100

GCD(5, 100) = ( 5 x 100 ) / 100

= 5 / 100

= 5

Step3:

LCM(5, 444) = 2220

GCD(5, 444) = ( 5 x 444 ) / 2220

= 5 / 444

= 5

So, Greatest Common Divisor of 405, 290, 100, 444 is 1
