Given numbers are 538, 260, 320, 815

The list of prime factors of all numbers are

Prime factors of 538 are 2 x 269

Prime factors of 260 are 2 x 2 x 5 x 13

Prime factors of 320 are 2 x 2 x 2 x 2 x 2 x 2 x 5

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 538, 260, 320, 815

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

Apply this formula for all numbers.

Step1:

LCM(538, 260) = 69940

GCD(538, 260) = ( 538 x 260 ) / 69940

= 538 / 260

= 538

Step2:

LCM(2, 320) = 320

GCD(2, 320) = ( 2 x 320 ) / 320

= 2 / 320

= 2

Step3:

LCM(2, 815) = 1630

GCD(2, 815) = ( 2 x 815 ) / 1630

= 2 / 815

= 2

So, Greatest Common Divisor of 538, 260, 320, 815 is 1
