Given numbers are 86, 15, 34, 13

The list of prime factors of all numbers are

Prime factors of 86 are 2 x 43

Prime factors of 15 are 3 x 5

Prime factors of 34 are 2 x 17

Prime factors of 13 are 13

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

Given numbers are 86, 15, 34, 13

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

Apply this formula for all numbers.

Step1:

LCM(86, 15) = 1290

GCD(86, 15) = ( 86 x 15 ) / 1290

= 86 / 15

= 86

Step2:

LCM(1, 34) = 34

GCD(1, 34) = ( 1 x 34 ) / 34

= 1 / 34

= 1

Step3:

LCM(1, 13) = 13

GCD(1, 13) = ( 1 x 13 ) / 13

= 1 / 13

= 1

So, Greatest Common Divisor of 86, 15, 34, 13 is 1
