Therefore, GCD of numbers 770, 781, 75, 625 is 1

Given Input Data is 770, 781, 75, 625

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 781 is 11 x 71

Prime Factorization of 75 is 3 x 5 x 5

Prime Factorization of 625 is 5 x 5 x 5 x 5

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(770, 781) = 54670

GCD(770, 781) = ( 770 x 781 ) / 54670

GCD(770, 781) = 601370 / 54670

GCD(770, 781) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 75

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

LCM(11, 75) = 825

GCD(11, 75) = ( 11 x 75 ) / 825

GCD(11, 75) = 825 / 825

GCD(11, 75) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 625

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

LCM(1, 625) = 625

GCD(1, 625) = ( 1 x 625 ) / 625

GCD(1, 625) = 625 / 625

GCD(1, 625) = 1

GCD of 770, 781, 75, 625 is 1
