Given numbers are 903, 622, 990, 815

The list of prime factors of all numbers are

Prime factors of 903 are 3 x 7 x 43

Prime factors of 622 are 2 x 311

Prime factors of 990 are 2 x 3 x 3 x 5 x 11

Prime factors of 815 are 5 x 163

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

Given numbers are 903, 622, 990, 815

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

Apply this formula for all numbers.

Step1:

LCM(903, 622) = 561666

GCD(903, 622) = ( 903 x 622 ) / 561666

= 903 / 622

= 903

Step2:

LCM(1, 990) = 990

GCD(1, 990) = ( 1 x 990 ) / 990

= 1 / 990

= 1

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 903, 622, 990, 815 is 1
