Given numbers are 860, 545, 721, 115

The list of prime factors of all numbers are

Prime factors of 860 are 2 x 2 x 5 x 43

Prime factors of 545 are 5 x 109

Prime factors of 721 are 7 x 103

Prime factors of 115 are 5 x 23

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

Given numbers are 860, 545, 721, 115

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

Apply this formula for all numbers.

Step1:

LCM(860, 545) = 93740

GCD(860, 545) = ( 860 x 545 ) / 93740

= 860 / 545

= 860

Step2:

LCM(5, 721) = 3605

GCD(5, 721) = ( 5 x 721 ) / 3605

= 5 / 721

= 5

Step3:

LCM(1, 115) = 115

GCD(1, 115) = ( 1 x 115 ) / 115

= 1 / 115

= 1

So, Greatest Common Divisor of 860, 545, 721, 115 is 1
