Therefore, GCD of numbers 870, 620, 67 is 1

Given Input Data is 870, 620, 67

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

Prime Factorization of 870 is 2 x 3 x 5 x 29

Prime Factorization of 620 is 2 x 2 x 5 x 31

Prime Factorization of 67 is 67

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(870, 620) = 53940

GCD(870, 620) = ( 870 x 620 ) / 53940

GCD(870, 620) = 539400 / 53940

GCD(870, 620) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 67

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

LCM(10, 67) = 670

GCD(10, 67) = ( 10 x 67 ) / 670

GCD(10, 67) = 670 / 670

GCD(10, 67) = 1

GCD of 870, 620, 67 is 1
