Given Input Data is 386, 740, 165, 715

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

Prime Factorization of 386 is 2 x 193

Prime Factorization of 740 is 2 x 2 x 5 x 37

Prime Factorization of 165 is 3 x 5 x 11

Prime Factorization of 715 is 5 x 11 x 13

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(386, 740) = 142820

GCD(386, 740) = ( 386 x 740 ) / 142820

GCD(386, 740) = 285640 / 142820

GCD(386, 740) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 165

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

LCM(2, 165) = 330

GCD(2, 165) = ( 2 x 165 ) / 330

GCD(2, 165) = 330 / 330

GCD(2, 165) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 715

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

LCM(1, 715) = 715

GCD(1, 715) = ( 1 x 715 ) / 715

GCD(1, 715) = 715 / 715

GCD(1, 715) = 1

GCD of 386, 740, 165, 715 is 1
