Given Input Data is 620, 895, 841, 980

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

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

Prime Factorization of 895 is 5 x 179

Prime Factorization of 841 is 29 x 29

Prime Factorization of 980 is 2 x 2 x 5 x 7 x 7

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(620, 895) = 110980

GCD(620, 895) = ( 620 x 895 ) / 110980

GCD(620, 895) = 554900 / 110980

GCD(620, 895) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 841

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

LCM(5, 841) = 4205

GCD(5, 841) = ( 5 x 841 ) / 4205

GCD(5, 841) = 4205 / 4205

GCD(5, 841) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 980

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

LCM(1, 980) = 980

GCD(1, 980) = ( 1 x 980 ) / 980

GCD(1, 980) = 980 / 980

GCD(1, 980) = 1

GCD of 620, 895, 841, 980 is 1
