Given Input numbers are 64, 40, 55

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

Divisors of 64 :

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

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

Divisors of 40 :

The positive integer divisors of 40 that completely divides 40 are.

1, 2, 4, 5, 8, 10, 20, 40

Divisors of 55 :

The positive integer divisors of 55 that completely divides 55 are.

1, 5, 11, 55

GCD of numbers is the greatest common divisor

So, the GCD (64, 40, 55) = 1.

Given numbers are 64, 40, 55

The list of prime factors of all numbers are

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

Prime factors of 40 are 2 x 2 x 2 x 5

Prime factors of 55 are 5 x 11

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

Given numbers are 64, 40, 55

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

Apply this formula for all numbers.

Step1:

LCM(64, 40) = 320

GCD(64, 40) = ( 64 x 40 ) / 320

= 64 / 40

= 64

Step2:

LCM(8, 55) = 440

GCD(8, 55) = ( 8 x 55 ) / 440

= 8 / 55

= 8

So, Greatest Common Divisor of 64, 40, 55 is 1
