Therefore, GCD of numbers 480, 620, 278, 411 is 1

Given Input Data is 480, 620, 278, 411

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

Prime Factorization of 480 is 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime Factorization of 620 is 2 x 2 x 5 x 31

Prime Factorization of 278 is 2 x 139

Prime Factorization of 411 is 3 x 137

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(480, 620) = 14880

GCD(480, 620) = ( 480 x 620 ) / 14880

GCD(480, 620) = 297600 / 14880

GCD(480, 620) = 20

Step2:

Here we consider the GCD from the above i.e. 20 as first number and the next as 278

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

LCM(20, 278) = 2780

GCD(20, 278) = ( 20 x 278 ) / 2780

GCD(20, 278) = 5560 / 2780

GCD(20, 278) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 411

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

LCM(2, 411) = 822

GCD(2, 411) = ( 2 x 411 ) / 822

GCD(2, 411) = 822 / 822

GCD(2, 411) = 1

GCD of 480, 620, 278, 411 is 1
