1, 2, 151, 302
Greatest Common Divisior
We found the divisors of 455, 784, 86, 302 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 455, 784, 86, 302 is 1.
Therefore, GCD of numbers 455, 784, 86, 302 is 1
Given Input Data is 455, 784, 86, 302
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 455 is 5 x 7 x 13
Prime Factorization of 784 is 2 x 2 x 2 x 2 x 7 x 7
Prime Factorization of 86 is 2 x 43
Prime Factorization of 302 is 2 x 151
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(455, 784) = 50960
GCD(455, 784) = ( 455 x 784 ) / 50960
GCD(455, 784) = 356720 / 50960
GCD(455, 784) = 7
Step2:
Here we consider the GCD from the above i.e. 7 as first number and the next as 86
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(7, 86) = 602
GCD(7, 86) = ( 7 x 86 ) / 602
GCD(7, 86) = 602 / 602
GCD(7, 86) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 302
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 302) = 302
GCD(1, 302) = ( 1 x 302 ) / 302
GCD(1, 302) = 302 / 302
GCD(1, 302) = 1
GCD of 455, 784, 86, 302 is 1
