GCD of 7, 31, 85 Calculator

Given Input numbers are 7, 31, 85

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

Divisors of 7 :

The positive integer divisors of 7 that completely divides 7 are.

1, 7

Divisors of 31 :

The positive integer divisors of 31 that completely divides 31 are.

1, 31

Divisors of 85 :

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

1, 5, 17, 85

GCD of numbers is the greatest common divisor

So, the GCD (7, 31, 85) = 1.

Given numbers are 7, 31, 85

The list of prime factors of all numbers are

Prime factors of 7 are 7

Prime factors of 31 are 31

Prime factors of 85 are 5 x 17

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

Given numbers are 7, 31, 85

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

Apply this formula for all numbers.

Step1:

LCM(7, 31) = 217

GCD(7, 31) = ( 7 x 31 ) / 217

= 7 / 31

= 7

Step2:

LCM(1, 85) = 85

GCD(1, 85) = ( 1 x 85 ) / 85

= 1 / 85

= 1

So, Greatest Common Divisor of 7, 31, 85 is 1
