Make use of GCD Calculator to determine the Greatest Common Divisor of 647, 163, 130, 787 i.e. 1 largest integer that divides all the numbers equally.
GCD of 647, 163, 130, 787 is 1
GCD(647, 163, 130, 787) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 647, 163, 130, 787 is 1
GCD(647, 163, 130, 787) = 1
Given Input numbers are 647, 163, 130, 787
To find the GCD of numbers using factoring list out all the divisors of each number

Greatest Common Divisior
We found the divisors of 647, 163, 130, 787 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 647, 163, 130, 787 is 1.
Therefore, GCD of numbers 647, 163, 130, 787 is 1
Given Input Data is 647, 163, 130, 787
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 647 is 647
Prime Factorization of 163 is 163
Prime Factorization of 130 is 2 x 5 x 13
Prime Factorization of 787 is 787
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(647, 163) = 105461
GCD(647, 163) = ( 647 x 163 ) / 105461
GCD(647, 163) = 105461 / 105461
GCD(647, 163) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 130
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 130) = 130
GCD(1, 130) = ( 1 x 130 ) / 130
GCD(1, 130) = 130 / 130
GCD(1, 130) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 787
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 787) = 787
GCD(1, 787) = ( 1 x 787 ) / 787
GCD(1, 787) = 787 / 787
GCD(1, 787) = 1
GCD of 647, 163, 130, 787 is 1
