Therefore, GCD of numbers 936, 915, 788, 778 is 1

Given Input Data is 936, 915, 788, 778

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

Prime Factorization of 936 is 2 x 2 x 2 x 3 x 3 x 13

Prime Factorization of 915 is 3 x 5 x 61

Prime Factorization of 788 is 2 x 2 x 197

Prime Factorization of 778 is 2 x 389

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(936, 915) = 285480

GCD(936, 915) = ( 936 x 915 ) / 285480

GCD(936, 915) = 856440 / 285480

GCD(936, 915) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 788

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

LCM(3, 788) = 2364

GCD(3, 788) = ( 3 x 788 ) / 2364

GCD(3, 788) = 2364 / 2364

GCD(3, 788) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 778

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

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

GCD(1, 778) = 778 / 778

GCD(1, 778) = 1

GCD of 936, 915, 788, 778 is 1
