Therefore, GCD of numbers 91, 455, 153, 960 is 1

Given Input Data is 91, 455, 153, 960

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

Prime Factorization of 91 is 7 x 13

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 153 is 3 x 3 x 17

Prime Factorization of 960 is 2 x 2 x 2 x 2 x 2 x 2 x 3 x 5

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(91, 455) = 455

GCD(91, 455) = ( 91 x 455 ) / 455

GCD(91, 455) = 41405 / 455

GCD(91, 455) = 91

Step2:

Here we consider the GCD from the above i.e. 91 as first number and the next as 153

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

LCM(91, 153) = 13923

GCD(91, 153) = ( 91 x 153 ) / 13923

GCD(91, 153) = 13923 / 13923

GCD(91, 153) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 960

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

LCM(1, 960) = 960

GCD(1, 960) = ( 1 x 960 ) / 960

GCD(1, 960) = 960 / 960

GCD(1, 960) = 1

GCD of 91, 455, 153, 960 is 1
