Make use of GCD Calculator to determine the Greatest Common Divisor of 625, 121, 18, 357 i.e. 1 largest integer that divides all the numbers equally.
GCD of 625, 121, 18, 357 is 1
GCD(625, 121, 18, 357) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 625, 121, 18, 357 is 1
GCD(625, 121, 18, 357) = 1
Given Input numbers are 625, 121, 18, 357
To find the GCD of numbers using factoring list out all the divisors of each number

Greatest Common Divisior
We found the divisors of 625, 121, 18, 357 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 625, 121, 18, 357 is 1.
Therefore, GCD of numbers 625, 121, 18, 357 is 1
Given Input Data is 625, 121, 18, 357
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 625 is 5 x 5 x 5 x 5
Prime Factorization of 121 is 11 x 11
Prime Factorization of 18 is 2 x 3 x 3
Prime Factorization of 357 is 3 x 7 x 17
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(625, 121) = 75625
GCD(625, 121) = ( 625 x 121 ) / 75625
GCD(625, 121) = 75625 / 75625
GCD(625, 121) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 18
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 18) = 18
GCD(1, 18) = ( 1 x 18 ) / 18
GCD(1, 18) = 18 / 18
GCD(1, 18) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 357
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 357) = 357
GCD(1, 357) = ( 1 x 357 ) / 357
GCD(1, 357) = 357 / 357
GCD(1, 357) = 1
GCD of 625, 121, 18, 357 is 1
