Given Input Data is 253, 858, 98, 825

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

Prime Factorization of 253 is 11 x 23

Prime Factorization of 858 is 2 x 3 x 11 x 13

Prime Factorization of 98 is 2 x 7 x 7

Prime Factorization of 825 is 3 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(253, 858) = 19734

GCD(253, 858) = ( 253 x 858 ) / 19734

GCD(253, 858) = 217074 / 19734

GCD(253, 858) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 98

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

LCM(11, 98) = 1078

GCD(11, 98) = ( 11 x 98 ) / 1078

GCD(11, 98) = 1078 / 1078

GCD(11, 98) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 825

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

LCM(1, 825) = 825

GCD(1, 825) = ( 1 x 825 ) / 825

GCD(1, 825) = 825 / 825

GCD(1, 825) = 1

GCD of 253, 858, 98, 825 is 1
