Therefore, GCD of numbers 865, 670, 52, 685 is 1

Given Input Data is 865, 670, 52, 685

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

Prime Factorization of 865 is 5 x 173

Prime Factorization of 670 is 2 x 5 x 67

Prime Factorization of 52 is 2 x 2 x 13

Prime Factorization of 685 is 5 x 137

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(865, 670) = 115910

GCD(865, 670) = ( 865 x 670 ) / 115910

GCD(865, 670) = 579550 / 115910

GCD(865, 670) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 52

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

LCM(5, 52) = 260

GCD(5, 52) = ( 5 x 52 ) / 260

GCD(5, 52) = 260 / 260

GCD(5, 52) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 685

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

LCM(1, 685) = 685

GCD(1, 685) = ( 1 x 685 ) / 685

GCD(1, 685) = 685 / 685

GCD(1, 685) = 1

GCD of 865, 670, 52, 685 is 1
