Therefore, GCD of numbers 455, 502, 244, 782 is 1

Given Input Data is 455, 502, 244, 782

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

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 502 is 2 x 251

Prime Factorization of 244 is 2 x 2 x 61

Prime Factorization of 782 is 2 x 17 x 23

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(455, 502) = 228410

GCD(455, 502) = ( 455 x 502 ) / 228410

GCD(455, 502) = 228410 / 228410

GCD(455, 502) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 244

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

LCM(1, 244) = 244

GCD(1, 244) = ( 1 x 244 ) / 244

GCD(1, 244) = 244 / 244

GCD(1, 244) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 782

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

LCM(1, 782) = 782

GCD(1, 782) = ( 1 x 782 ) / 782

GCD(1, 782) = 782 / 782

GCD(1, 782) = 1

GCD of 455, 502, 244, 782 is 1
