Given Input Data is 770, 255, 385

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

Prime Factorization of 770 is 2 x 5 x 7 x 11

Prime Factorization of 255 is 3 x 5 x 17

Prime Factorization of 385 is 5 x 7 x 11

Highest common occurrences in the given inputs are 5¹

Multiplying them we get the GCD as 5

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(770, 255) = 39270

GCD(770, 255) = ( 770 x 255 ) / 39270

GCD(770, 255) = 196350 / 39270

GCD(770, 255) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 385

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

LCM(5, 385) = 385

GCD(5, 385) = ( 5 x 385 ) / 385

GCD(5, 385) = 1925 / 385

GCD(5, 385) = 5

GCD of 770, 255, 385 is 5
