Therefore, GCD of numbers 665, 707, 266, 438 is 1

Given Input Data is 665, 707, 266, 438

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 707 is 7 x 101

Prime Factorization of 266 is 2 x 7 x 19

Prime Factorization of 438 is 2 x 3 x 73

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, 707) = 67165

GCD(665, 707) = ( 665 x 707 ) / 67165

GCD(665, 707) = 470155 / 67165

GCD(665, 707) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 266

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

LCM(7, 266) = 266

GCD(7, 266) = ( 7 x 266 ) / 266

GCD(7, 266) = 1862 / 266

GCD(7, 266) = 7

Step3:

Here we consider the GCD from the above i.e. 7 as first number and the next as 438

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

LCM(7, 438) = 3066

GCD(7, 438) = ( 7 x 438 ) / 3066

GCD(7, 438) = 3066 / 3066

GCD(7, 438) = 1

GCD of 665, 707, 266, 438 is 1
