Therefore, GCD of numbers 611, 343, 28, 550 is 1

Given Input Data is 611, 343, 28, 550

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

Prime Factorization of 611 is 13 x 47

Prime Factorization of 343 is 7 x 7 x 7

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 550 is 2 x 5 x 5 x 11

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(611, 343) = 209573

GCD(611, 343) = ( 611 x 343 ) / 209573

GCD(611, 343) = 209573 / 209573

GCD(611, 343) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 28

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

LCM(1, 28) = 28

GCD(1, 28) = ( 1 x 28 ) / 28

GCD(1, 28) = 28 / 28

GCD(1, 28) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 550

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

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

GCD(1, 550) = 550 / 550

GCD(1, 550) = 1

GCD of 611, 343, 28, 550 is 1
