Therefore, GCD of numbers 65, 870, 646, 372 is 1

Given Input Data is 65, 870, 646, 372

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

Prime Factorization of 65 is 5 x 13

Prime Factorization of 870 is 2 x 3 x 5 x 29

Prime Factorization of 646 is 2 x 17 x 19

Prime Factorization of 372 is 2 x 2 x 3 x 31

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(65, 870) = 11310

GCD(65, 870) = ( 65 x 870 ) / 11310

GCD(65, 870) = 56550 / 11310

GCD(65, 870) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 646

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

LCM(5, 646) = 3230

GCD(5, 646) = ( 5 x 646 ) / 3230

GCD(5, 646) = 3230 / 3230

GCD(5, 646) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 372

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

LCM(1, 372) = 372

GCD(1, 372) = ( 1 x 372 ) / 372

GCD(1, 372) = 372 / 372

GCD(1, 372) = 1

GCD of 65, 870, 646, 372 is 1
