Therefore, GCD of numbers 665, 437, 64, 357 is 1

Given Input Data is 665, 437, 64, 357

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 665 is 5 x 7 x 19

Prime Factorization of 437 is 19 x 23

Prime Factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 357 is 3 x 7 x 17

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

Step1:

Let's calculate the GCD of first two numbers

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

LCM(665, 437) = 15295

GCD(665, 437) = ( 665 x 437 ) / 15295

GCD(665, 437) = 290605 / 15295

GCD(665, 437) = 19

Step2:

Here we consider the GCD from the above i.e. 19 as first number and the next as 64

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

LCM(19, 64) = 1216

GCD(19, 64) = ( 19 x 64 ) / 1216

GCD(19, 64) = 1216 / 1216

GCD(19, 64) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 357

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

LCM(1, 357) = 357

GCD(1, 357) = ( 1 x 357 ) / 357

GCD(1, 357) = 357 / 357

GCD(1, 357) = 1

GCD of 665, 437, 64, 357 is 1
