Therefore, GCD of numbers 781, 374, 70, 318 is 1

Given Input Data is 781, 374, 70, 318

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

Prime Factorization of 781 is 11 x 71

Prime Factorization of 374 is 2 x 11 x 17

Prime Factorization of 70 is 2 x 5 x 7

Prime Factorization of 318 is 2 x 3 x 53

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(781, 374) = 26554

GCD(781, 374) = ( 781 x 374 ) / 26554

GCD(781, 374) = 292094 / 26554

GCD(781, 374) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 70

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

LCM(11, 70) = 770

GCD(11, 70) = ( 11 x 70 ) / 770

GCD(11, 70) = 770 / 770

GCD(11, 70) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 318

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

LCM(1, 318) = 318

GCD(1, 318) = ( 1 x 318 ) / 318

GCD(1, 318) = 318 / 318

GCD(1, 318) = 1

GCD of 781, 374, 70, 318 is 1
