GCD of 10, 43, 15, 91 Calculator

Given Input numbers are 10, 43, 15, 91

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

Divisors of 10 :

The positive integer divisors of 10 that completely divides 10 are.

1, 2, 5, 10

Divisors of 43 :

The positive integer divisors of 43 that completely divides 43 are.

1, 43

Divisors of 15 :

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

1, 3, 5, 15

Divisors of 91 :

The positive integer divisors of 91 that completely divides 91 are.

1, 7, 13, 91

GCD of numbers is the greatest common divisor

So, the GCD (10, 43, 15, 91) = 1.

Given numbers are 10, 43, 15, 91

The list of prime factors of all numbers are

Prime factors of 10 are 2 x 5

Prime factors of 43 are 43

Prime factors of 15 are 3 x 5

Prime factors of 91 are 7 x 13

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

Given numbers are 10, 43, 15, 91

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

Apply this formula for all numbers.

Step1:

LCM(10, 43) = 430

GCD(10, 43) = ( 10 x 43 ) / 430

= 10 / 43

= 10

Step2:

LCM(1, 15) = 15

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

= 1 / 15

= 1

Step3:

LCM(1, 91) = 91

GCD(1, 91) = ( 1 x 91 ) / 91

= 1 / 91

= 1

So, Greatest Common Divisor of 10, 43, 15, 91 is 1
