Given numbers are 200, 290, 391, 815

The list of prime factors of all numbers are

Prime factors of 200 are 2 x 2 x 2 x 5 x 5

Prime factors of 290 are 2 x 5 x 29

Prime factors of 391 are 17 x 23

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 200, 290, 391, 815

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

Apply this formula for all numbers.

Step1:

LCM(200, 290) = 5800

GCD(200, 290) = ( 200 x 290 ) / 5800

= 200 / 290

= 200

Step2:

LCM(10, 391) = 3910

GCD(10, 391) = ( 10 x 391 ) / 3910

= 10 / 391

= 10

Step3:

LCM(1, 815) = 815

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

= 1 / 815

= 1

So, Greatest Common Divisor of 200, 290, 391, 815 is 1
