Make use of GCD Calculator to determine the Greatest Common Divisor of 387, 143, 388, 393 i.e. 1 largest integer that divides all the numbers equally.
GCD of 387, 143, 388, 393 is 1
GCD(387, 143, 388, 393) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 387, 143, 388, 393 is 1
GCD(387, 143, 388, 393) = 1
Given Input numbers are 387, 143, 388, 393
To find the GCD of numbers using factoring list out all the divisors of each number

1, 3, 131, 393
Greatest Common Divisior
We found the divisors of 387, 143, 388, 393 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 387, 143, 388, 393 is 1.
Therefore, GCD of numbers 387, 143, 388, 393 is 1
Given Input Data is 387, 143, 388, 393
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 387 is 3 x 3 x 43
Prime Factorization of 143 is 11 x 13
Prime Factorization of 388 is 2 x 2 x 97
Prime Factorization of 393 is 3 x 131
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(387, 143) = 55341
GCD(387, 143) = ( 387 x 143 ) / 55341
GCD(387, 143) = 55341 / 55341
GCD(387, 143) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 388
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 388) = 388
GCD(1, 388) = ( 1 x 388 ) / 388
GCD(1, 388) = 388 / 388
GCD(1, 388) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 393
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 393) = 393
GCD(1, 393) = ( 1 x 393 ) / 393
GCD(1, 393) = 393 / 393
GCD(1, 393) = 1
GCD of 387, 143, 388, 393 is 1
