Given numbers are 815, 204, 909, 121

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 204 are 2 x 2 x 3 x 17

Prime factors of 909 are 3 x 3 x 101

Prime factors of 121 are 11 x 11

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

Given numbers are 815, 204, 909, 121

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

Apply this formula for all numbers.

Step1:

LCM(815, 204) = 166260

GCD(815, 204) = ( 815 x 204 ) / 166260

= 815 / 204

= 815

Step2:

LCM(1, 909) = 909

GCD(1, 909) = ( 1 x 909 ) / 909

= 1 / 909

= 1

Step3:

LCM(1, 121) = 121

GCD(1, 121) = ( 1 x 121 ) / 121

= 1 / 121

= 1

So, Greatest Common Divisor of 815, 204, 909, 121 is 1
