Therefore, GCD of numbers 770, 525, 840, 787 is 1

Given Input Data is 770, 525, 840, 787

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 525 is 3 x 5 x 5 x 7

Prime Factorization of 840 is 2 x 2 x 2 x 3 x 5 x 7

Prime Factorization of 787 is 787

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, 525) = 11550

GCD(770, 525) = ( 770 x 525 ) / 11550

GCD(770, 525) = 404250 / 11550

GCD(770, 525) = 35

Step2:

Here we consider the GCD from the above i.e. 35 as first number and the next as 840

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

LCM(35, 840) = 840

GCD(35, 840) = ( 35 x 840 ) / 840

GCD(35, 840) = 29400 / 840

GCD(35, 840) = 35

Step3:

Here we consider the GCD from the above i.e. 35 as first number and the next as 787

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

LCM(35, 787) = 27545

GCD(35, 787) = ( 35 x 787 ) / 27545

GCD(35, 787) = 27545 / 27545

GCD(35, 787) = 1

GCD of 770, 525, 840, 787 is 1
