Therefore, GCD of numbers 786, 186, 878, 781 is 1

Given Input Data is 786, 186, 878, 781

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

Prime Factorization of 786 is 2 x 3 x 131

Prime Factorization of 186 is 2 x 3 x 31

Prime Factorization of 878 is 2 x 439

Prime Factorization of 781 is 11 x 71

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(786, 186) = 24366

GCD(786, 186) = ( 786 x 186 ) / 24366

GCD(786, 186) = 146196 / 24366

GCD(786, 186) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 878

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

LCM(6, 878) = 2634

GCD(6, 878) = ( 6 x 878 ) / 2634

GCD(6, 878) = 5268 / 2634

GCD(6, 878) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 781

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

LCM(2, 781) = 1562

GCD(2, 781) = ( 2 x 781 ) / 1562

GCD(2, 781) = 1562 / 1562

GCD(2, 781) = 1

GCD of 786, 186, 878, 781 is 1
