GCD of 15, 16, 64, 22 Calculator

Given Input numbers are 15, 16, 64, 22

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

Divisors of 15 :

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

1, 3, 5, 15

Divisors of 16 :

The positive integer divisors of 16 that completely divides 16 are.

1, 2, 4, 8, 16

Divisors of 64 :

The positive integer divisors of 64 that completely divides 64 are.

1, 2, 4, 8, 16, 32, 64

Divisors of 22 :

The positive integer divisors of 22 that completely divides 22 are.

1, 2, 11, 22

GCD of numbers is the greatest common divisor

So, the GCD (15, 16, 64, 22) = 1.

Given numbers are 15, 16, 64, 22

The list of prime factors of all numbers are

Prime factors of 15 are 3 x 5

Prime factors of 16 are 2 x 2 x 2 x 2

Prime factors of 64 are 2 x 2 x 2 x 2 x 2 x 2

Prime factors of 22 are 2 x 11

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

Given numbers are 15, 16, 64, 22

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

Apply this formula for all numbers.

Step1:

LCM(15, 16) = 240

GCD(15, 16) = ( 15 x 16 ) / 240

= 15 / 16

= 15

Step2:

LCM(1, 64) = 64

GCD(1, 64) = ( 1 x 64 ) / 64

= 1 / 64

= 1

Step3:

LCM(1, 22) = 22

GCD(1, 22) = ( 1 x 22 ) / 22

= 1 / 22

= 1

So, Greatest Common Divisor of 15, 16, 64, 22 is 1
