Given numbers are 115, 134, 180, 691

The list of prime factors of all numbers are

Prime factors of 115 are 5 x 23

Prime factors of 134 are 2 x 67

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 691 are 691

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

Given numbers are 115, 134, 180, 691

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

Apply this formula for all numbers.

Step1:

LCM(115, 134) = 15410

GCD(115, 134) = ( 115 x 134 ) / 15410

= 115 / 134

= 115

Step2:

LCM(1, 180) = 180

GCD(1, 180) = ( 1 x 180 ) / 180

= 1 / 180

= 1

Step3:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

So, Greatest Common Divisor of 115, 134, 180, 691 is 1
