Given numbers are 115, 520, 887, 440

The list of prime factors of all numbers are

Prime factors of 115 are 5 x 23

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 887 are 887

Prime factors of 440 are 2 x 2 x 2 x 5 x 11

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

Given numbers are 115, 520, 887, 440

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

Apply this formula for all numbers.

Step1:

LCM(115, 520) = 11960

GCD(115, 520) = ( 115 x 520 ) / 11960

= 115 / 520

= 115

Step2:

LCM(5, 887) = 4435

GCD(5, 887) = ( 5 x 887 ) / 4435

= 5 / 887

= 5

Step3:

LCM(1, 440) = 440

GCD(1, 440) = ( 1 x 440 ) / 440

= 1 / 440

= 1

So, Greatest Common Divisor of 115, 520, 887, 440 is 1
