Given Input Data is 865, 920, 141

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

Prime Factorization of 865 is 5 x 173

Prime Factorization of 920 is 2 x 2 x 2 x 5 x 23

Prime Factorization of 141 is 3 x 47

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, 920) = 159160

GCD(865, 920) = ( 865 x 920 ) / 159160

GCD(865, 920) = 795800 / 159160

GCD(865, 920) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 141

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

LCM(5, 141) = 705

GCD(5, 141) = ( 5 x 141 ) / 705

GCD(5, 141) = 705 / 705

GCD(5, 141) = 1

GCD of 865, 920, 141 is 1
