Therefore, GCD of numbers 102, 786, 85, 290 is 1

Given Input Data is 102, 786, 85, 290

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

Prime Factorization of 102 is 2 x 3 x 17

Prime Factorization of 786 is 2 x 3 x 131

Prime Factorization of 85 is 5 x 17

Prime Factorization of 290 is 2 x 5 x 29

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(102, 786) = 13362

GCD(102, 786) = ( 102 x 786 ) / 13362

GCD(102, 786) = 80172 / 13362

GCD(102, 786) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 85

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

LCM(6, 85) = 510

GCD(6, 85) = ( 6 x 85 ) / 510

GCD(6, 85) = 510 / 510

GCD(6, 85) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 290

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

LCM(1, 290) = 290

GCD(1, 290) = ( 1 x 290 ) / 290

GCD(1, 290) = 290 / 290

GCD(1, 290) = 1

GCD of 102, 786, 85, 290 is 1
