Greatest Common Divisior
We found the divisors of 262, 231, 390, 840 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 262, 231, 390, 840 is 1.
Therefore, GCD of numbers 262, 231, 390, 840 is 1
Given Input Data is 262, 231, 390, 840
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 262 is 2 x 131
Prime Factorization of 231 is 3 x 7 x 11
Prime Factorization of 390 is 2 x 3 x 5 x 13
Prime Factorization of 840 is 2 x 2 x 2 x 3 x 5 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(262, 231) = 60522
GCD(262, 231) = ( 262 x 231 ) / 60522
GCD(262, 231) = 60522 / 60522
GCD(262, 231) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 390
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 390) = 390
GCD(1, 390) = ( 1 x 390 ) / 390
GCD(1, 390) = 390 / 390
GCD(1, 390) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 840
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
GCD(1, 840) = 840 / 840
GCD(1, 840) = 1
GCD of 262, 231, 390, 840 is 1
