Therefore, GCD of numbers 946, 517, 49, 620 is 1

Given Input Data is 946, 517, 49, 620

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

Prime Factorization of 946 is 2 x 11 x 43

Prime Factorization of 517 is 11 x 47

Prime Factorization of 49 is 7 x 7

Prime Factorization of 620 is 2 x 2 x 5 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(946, 517) = 44462

GCD(946, 517) = ( 946 x 517 ) / 44462

GCD(946, 517) = 489082 / 44462

GCD(946, 517) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 49

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

LCM(11, 49) = 539

GCD(11, 49) = ( 11 x 49 ) / 539

GCD(11, 49) = 539 / 539

GCD(11, 49) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 620

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

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

GCD(1, 620) = 620 / 620

GCD(1, 620) = 1

GCD of 946, 517, 49, 620 is 1
