Given numbers are 815, 560, 195, 203

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 560 are 2 x 2 x 2 x 2 x 5 x 7

Prime factors of 195 are 3 x 5 x 13

Prime factors of 203 are 7 x 29

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

Given numbers are 815, 560, 195, 203

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

Apply this formula for all numbers.

Step1:

LCM(815, 560) = 91280

GCD(815, 560) = ( 815 x 560 ) / 91280

= 815 / 560

= 815

Step2:

LCM(5, 195) = 195

GCD(5, 195) = ( 5 x 195 ) / 195

= 5 / 195

= 5

Step3:

LCM(5, 203) = 1015

GCD(5, 203) = ( 5 x 203 ) / 1015

= 5 / 203

= 5

So, Greatest Common Divisor of 815, 560, 195, 203 is 1
