Therefore, GCD of numbers 75, 411, 610, 770 is 1

Given Input Data is 75, 411, 610, 770

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

Prime Factorization of 75 is 3 x 5 x 5

Prime Factorization of 411 is 3 x 137

Prime Factorization of 610 is 2 x 5 x 61

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

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(75, 411) = 10275

GCD(75, 411) = ( 75 x 411 ) / 10275

GCD(75, 411) = 30825 / 10275

GCD(75, 411) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 610

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

LCM(3, 610) = 1830

GCD(3, 610) = ( 3 x 610 ) / 1830

GCD(3, 610) = 1830 / 1830

GCD(3, 610) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 770

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

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

GCD(1, 770) = 770 / 770

GCD(1, 770) = 1

GCD of 75, 411, 610, 770 is 1
