Therefore, GCD of numbers 989, 782, 70, 787 is 1

Given Input Data is 989, 782, 70, 787

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

Prime Factorization of 989 is 23 x 43

Prime Factorization of 782 is 2 x 17 x 23

Prime Factorization of 70 is 2 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(989, 782) = 33626

GCD(989, 782) = ( 989 x 782 ) / 33626

GCD(989, 782) = 773398 / 33626

GCD(989, 782) = 23

Step2:

Here we consider the GCD from the above i.e. 23 as first number and the next as 70

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

LCM(23, 70) = 1610

GCD(23, 70) = ( 23 x 70 ) / 1610

GCD(23, 70) = 1610 / 1610

GCD(23, 70) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 787

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

LCM(1, 787) = 787

GCD(1, 787) = ( 1 x 787 ) / 787

GCD(1, 787) = 787 / 787

GCD(1, 787) = 1

GCD of 989, 782, 70, 787 is 1
