Greatest Common Divisior
We found the divisors of 202, 681, 790, 490 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 202, 681, 790, 490 is 1.
Therefore, GCD of numbers 202, 681, 790, 490 is 1
Given Input Data is 202, 681, 790, 490
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 202 is 2 x 101
Prime Factorization of 681 is 3 x 227
Prime Factorization of 790 is 2 x 5 x 79
Prime Factorization of 490 is 2 x 5 x 7 x 7
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(202, 681) = 137562
GCD(202, 681) = ( 202 x 681 ) / 137562
GCD(202, 681) = 137562 / 137562
GCD(202, 681) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 790
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 790) = 790
GCD(1, 790) = ( 1 x 790 ) / 790
GCD(1, 790) = 790 / 790
GCD(1, 790) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 490
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 490) = 490
GCD(1, 490) = ( 1 x 490 ) / 490
GCD(1, 490) = 490 / 490
GCD(1, 490) = 1
GCD of 202, 681, 790, 490 is 1
