Given numbers are 115, 320, 613, 820

The list of prime factors of all numbers are

Prime factors of 115 are 5 x 23

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

Prime factors of 613 are 613

Prime factors of 820 are 2 x 2 x 5 x 41

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

Given numbers are 115, 320, 613, 820

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

Apply this formula for all numbers.

Step1:

LCM(115, 320) = 7360

GCD(115, 320) = ( 115 x 320 ) / 7360

= 115 / 320

= 115

Step2:

LCM(5, 613) = 3065

GCD(5, 613) = ( 5 x 613 ) / 3065

= 5 / 613

= 5

Step3:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 115, 320, 613, 820 is 1
