Therefore, GCD of numbers 140, 973, 52, 247 is 1

Given Input Data is 140, 973, 52, 247

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

Prime Factorization of 140 is 2 x 2 x 5 x 7

Prime Factorization of 973 is 7 x 139

Prime Factorization of 52 is 2 x 2 x 13

Prime Factorization of 247 is 13 x 19

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(140, 973) = 19460

GCD(140, 973) = ( 140 x 973 ) / 19460

GCD(140, 973) = 136220 / 19460

GCD(140, 973) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 52

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

LCM(7, 52) = 364

GCD(7, 52) = ( 7 x 52 ) / 364

GCD(7, 52) = 364 / 364

GCD(7, 52) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 247

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

LCM(1, 247) = 247

GCD(1, 247) = ( 1 x 247 ) / 247

GCD(1, 247) = 247 / 247

GCD(1, 247) = 1

GCD of 140, 973, 52, 247 is 1
