We found the divisors of 682, 553, 81, 154 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 682, 553, 81, 154 is 1.

Therefore, GCD of numbers 682, 553, 81, 154 is 1

Given Input Data is 682, 553, 81, 154

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

Prime Factorization of 682 is 2 x 11 x 31

Prime Factorization of 553 is 7 x 79

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 154 is 2 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(682, 553) = 377146

GCD(682, 553) = ( 682 x 553 ) / 377146

GCD(682, 553) = 377146 / 377146

GCD(682, 553) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 81

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

LCM(1, 81) = 81

GCD(1, 81) = ( 1 x 81 ) / 81

GCD(1, 81) = 81 / 81

GCD(1, 81) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 154

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

LCM(1, 154) = 154

GCD(1, 154) = ( 1 x 154 ) / 154

GCD(1, 154) = 154 / 154

GCD(1, 154) = 1

GCD of 682, 553, 81, 154 is 1
