Therefore, GCD of numbers 455, 637, 89, 919 is 1

Given Input Data is 455, 637, 89, 919

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 637 is 7 x 7 x 13

Prime Factorization of 89 is 89

Prime Factorization of 919 is 919

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, 637) = 3185

GCD(455, 637) = ( 455 x 637 ) / 3185

GCD(455, 637) = 289835 / 3185

GCD(455, 637) = 91

Step2:

Here we consider the GCD from the above i.e. 91 as first number and the next as 89

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

LCM(91, 89) = 8099

GCD(91, 89) = ( 91 x 89 ) / 8099

GCD(91, 89) = 8099 / 8099

GCD(91, 89) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 919

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

LCM(1, 919) = 919

GCD(1, 919) = ( 1 x 919 ) / 919

GCD(1, 919) = 919 / 919

GCD(1, 919) = 1

GCD of 455, 637, 89, 919 is 1
