Therefore, GCD of numbers 670, 785, 62, 398 is 1

Given Input Data is 670, 785, 62, 398

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

Prime Factorization of 670 is 2 x 5 x 67

Prime Factorization of 785 is 5 x 157

Prime Factorization of 62 is 2 x 31

Prime Factorization of 398 is 2 x 199

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(670, 785) = 105190

GCD(670, 785) = ( 670 x 785 ) / 105190

GCD(670, 785) = 525950 / 105190

GCD(670, 785) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 62

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

LCM(5, 62) = 310

GCD(5, 62) = ( 5 x 62 ) / 310

GCD(5, 62) = 310 / 310

GCD(5, 62) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 398

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

LCM(1, 398) = 398

GCD(1, 398) = ( 1 x 398 ) / 398

GCD(1, 398) = 398 / 398

GCD(1, 398) = 1

GCD of 670, 785, 62, 398 is 1
