Make use of GCD Calculator to determine the Greatest Common Divisor of 128, 771, 44, 631 i.e. 1 largest integer that divides all the numbers equally.
GCD of 128, 771, 44, 631 is 1
GCD(128, 771, 44, 631) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 128, 771, 44, 631 is 1
GCD(128, 771, 44, 631) = 1
Given Input numbers are 128, 771, 44, 631
To find the GCD of numbers using factoring list out all the divisors of each number

1, 631
Greatest Common Divisior
We found the divisors of 128, 771, 44, 631 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 128, 771, 44, 631 is 1.
Therefore, GCD of numbers 128, 771, 44, 631 is 1
Given Input Data is 128, 771, 44, 631
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2
Prime Factorization of 771 is 3 x 257
Prime Factorization of 44 is 2 x 2 x 11
Prime Factorization of 631 is 631
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(128, 771) = 98688
GCD(128, 771) = ( 128 x 771 ) / 98688
GCD(128, 771) = 98688 / 98688
GCD(128, 771) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 44
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 44) = 44
GCD(1, 44) = ( 1 x 44 ) / 44
GCD(1, 44) = 44 / 44
GCD(1, 44) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 631
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 631) = 631
GCD(1, 631) = ( 1 x 631 ) / 631
GCD(1, 631) = 631 / 631
GCD(1, 631) = 1
GCD of 128, 771, 44, 631 is 1
