GCD of 14, 85, 15, 30 Calculator

Given Input numbers are 14, 85, 15, 30

In the factoring method, we have to find the divisors of all numbers

Divisors of 14 :

The positive integer divisors of 14 that completely divides 14 are.

1, 2, 7, 14

Divisors of 85 :

The positive integer divisors of 85 that completely divides 85 are.

1, 5, 17, 85

Divisors of 15 :

The positive integer divisors of 15 that completely divides 15 are.

1, 3, 5, 15

Divisors of 30 :

The positive integer divisors of 30 that completely divides 30 are.

1, 2, 3, 5, 6, 10, 15, 30

GCD of numbers is the greatest common divisor

So, the GCD (14, 85, 15, 30) = 1.

Given numbers are 14, 85, 15, 30

The list of prime factors of all numbers are

Prime factors of 14 are 2 x 7

Prime factors of 85 are 5 x 17

Prime factors of 15 are 3 x 5

Prime factors of 30 are 2 x 3 x 5

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

Given numbers are 14, 85, 15, 30

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

Apply this formula for all numbers.

Step1:

LCM(14, 85) = 1190

GCD(14, 85) = ( 14 x 85 ) / 1190

= 14 / 85

= 14

Step2:

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

= 1 / 15

= 1

Step3:

LCM(1, 30) = 30

GCD(1, 30) = ( 1 x 30 ) / 30

= 1 / 30

= 1

So, Greatest Common Divisor of 14, 85, 15, 30 is 1
