Given numbers are 207, 405, 900, 730

The list of prime factors of all numbers are

Prime factors of 207 are 3 x 3 x 23

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

Prime factors of 900 are 2 x 2 x 3 x 3 x 5 x 5

Prime factors of 730 are 2 x 5 x 73

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

Given numbers are 207, 405, 900, 730

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

Apply this formula for all numbers.

Step1:

LCM(207, 405) = 9315

GCD(207, 405) = ( 207 x 405 ) / 9315

= 207 / 405

= 207

Step2:

LCM(9, 900) = 900

GCD(9, 900) = ( 9 x 900 ) / 900

= 9 / 900

= 9

Step3:

LCM(9, 730) = 6570

GCD(9, 730) = ( 9 x 730 ) / 6570

= 9 / 730

= 9

So, Greatest Common Divisor of 207, 405, 900, 730 is 1
