Make use of GCD Calculator to determine the Greatest Common Divisor of 469, 621, 14, 645 i.e. 1 largest integer that divides all the numbers equally.
GCD of 469, 621, 14, 645 is 1
GCD(469, 621, 14, 645) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 469, 621, 14, 645 is 1
GCD(469, 621, 14, 645) = 1
Given Input numbers are 469, 621, 14, 645
To find the GCD of numbers using factoring list out all the divisors of each number

Greatest Common Divisior
We found the divisors of 469, 621, 14, 645 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 469, 621, 14, 645 is 1.
Therefore, GCD of numbers 469, 621, 14, 645 is 1
Given Input Data is 469, 621, 14, 645
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 469 is 7 x 67
Prime Factorization of 621 is 3 x 3 x 3 x 23
Prime Factorization of 14 is 2 x 7
Prime Factorization of 645 is 3 x 5 x 43
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(469, 621) = 291249
GCD(469, 621) = ( 469 x 621 ) / 291249
GCD(469, 621) = 291249 / 291249
GCD(469, 621) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 14
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 14) = 14
GCD(1, 14) = ( 1 x 14 ) / 14
GCD(1, 14) = 14 / 14
GCD(1, 14) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 645
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
GCD(1, 645) = 645 / 645
GCD(1, 645) = 1
GCD of 469, 621, 14, 645 is 1
