Make use of GCD Calculator to determine the Greatest Common Divisor of 641, 263, 423, 747 i.e. 1 largest integer that divides all the numbers equally.
GCD of 641, 263, 423, 747 is 1
GCD(641, 263, 423, 747) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 641, 263, 423, 747 is 1
GCD(641, 263, 423, 747) = 1
Given Input numbers are 641, 263, 423, 747
To find the GCD of numbers using factoring list out all the divisors of each number

1, 3, 9, 83, 249, 747
Greatest Common Divisior
We found the divisors of 641, 263, 423, 747 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 641, 263, 423, 747 is 1.
Therefore, GCD of numbers 641, 263, 423, 747 is 1
Given Input Data is 641, 263, 423, 747
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 641 is 641
Prime Factorization of 263 is 263
Prime Factorization of 423 is 3 x 3 x 47
Prime Factorization of 747 is 3 x 3 x 83
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(641, 263) = 168583
GCD(641, 263) = ( 641 x 263 ) / 168583
GCD(641, 263) = 168583 / 168583
GCD(641, 263) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 423
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 423) = 423
GCD(1, 423) = ( 1 x 423 ) / 423
GCD(1, 423) = 423 / 423
GCD(1, 423) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 747
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 747) = 747
GCD(1, 747) = ( 1 x 747 ) / 747
GCD(1, 747) = 747 / 747
GCD(1, 747) = 1
GCD of 641, 263, 423, 747 is 1
