1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
Greatest Common Divisior
We found the divisors of 406, 343, 778, 760 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 406, 343, 778, 760 is 1.
Therefore, GCD of numbers 406, 343, 778, 760 is 1
Given Input Data is 406, 343, 778, 760
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 406 is 2 x 7 x 29
Prime Factorization of 343 is 7 x 7 x 7
Prime Factorization of 778 is 2 x 389
Prime Factorization of 760 is 2 x 2 x 2 x 5 x 19
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(406, 343) = 19894
GCD(406, 343) = ( 406 x 343 ) / 19894
GCD(406, 343) = 139258 / 19894
GCD(406, 343) = 7
Step2:
Here we consider the GCD from the above i.e. 7 as first number and the next as 778
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(7, 778) = 5446
GCD(7, 778) = ( 7 x 778 ) / 5446
GCD(7, 778) = 5446 / 5446
GCD(7, 778) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 760
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 760) = 760
GCD(1, 760) = ( 1 x 760 ) / 760
GCD(1, 760) = 760 / 760
GCD(1, 760) = 1
GCD of 406, 343, 778, 760 is 1
