Make use of GCD Calculator to determine the Greatest Common Divisor of 280, 385, 17, 419 i.e. 1 largest integer that divides all the numbers equally.
GCD of 280, 385, 17, 419 is 1
GCD(280, 385, 17, 419) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 280, 385, 17, 419 is 1
GCD(280, 385, 17, 419) = 1
Given Input numbers are 280, 385, 17, 419
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 280

1, 419
Greatest Common Divisior
We found the divisors of 280, 385, 17, 419 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 280, 385, 17, 419 is 1.
Therefore, GCD of numbers 280, 385, 17, 419 is 1
Given Input Data is 280, 385, 17, 419
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 280 is 2 x 2 x 2 x 5 x 7
Prime Factorization of 385 is 5 x 7 x 11
Prime Factorization of 17 is 17
Prime Factorization of 419 is 419
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(280, 385) = 3080
GCD(280, 385) = ( 280 x 385 ) / 3080
GCD(280, 385) = 107800 / 3080
GCD(280, 385) = 35
Step2:
Here we consider the GCD from the above i.e. 35 as first number and the next as 17
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(35, 17) = 595
GCD(35, 17) = ( 35 x 17 ) / 595
GCD(35, 17) = 595 / 595
GCD(35, 17) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 419
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 419) = 419
GCD(1, 419) = ( 1 x 419 ) / 419
GCD(1, 419) = 419 / 419
GCD(1, 419) = 1
GCD of 280, 385, 17, 419 is 1
