So the Greatest Common Divisior 651, 609, 653, 889 is 1.

Therefore, GCD of numbers 651, 609, 653, 889 is 1

Given Input Data is 651, 609, 653, 889

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

Prime Factorization of 651 is 3 x 7 x 31

Prime Factorization of 609 is 3 x 7 x 29

Prime Factorization of 653 is 653

Prime Factorization of 889 is 7 x 127

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(651, 609) = 18879

GCD(651, 609) = ( 651 x 609 ) / 18879

GCD(651, 609) = 396459 / 18879

GCD(651, 609) = 21

Step2:

Here we consider the GCD from the above i.e. 21 as first number and the next as 653

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

LCM(21, 653) = 13713

GCD(21, 653) = ( 21 x 653 ) / 13713

GCD(21, 653) = 13713 / 13713

GCD(21, 653) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 889

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

LCM(1, 889) = 889

GCD(1, 889) = ( 1 x 889 ) / 889

GCD(1, 889) = 889 / 889

GCD(1, 889) = 1

GCD of 651, 609, 653, 889 is 1
