Make use of GCD Calculator to determine the Greatest Common Divisor of 87, 641, 767, 640 i.e. 1 largest integer that divides all the numbers equally.
GCD of 87, 641, 767, 640 is 1
GCD(87, 641, 767, 640) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 87, 641, 767, 640 is 1
GCD(87, 641, 767, 640) = 1
Given Input numbers are 87, 641, 767, 640
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
Greatest Common Divisior
We found the divisors of 87, 641, 767, 640 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 87, 641, 767, 640 is 1.
Therefore, GCD of numbers 87, 641, 767, 640 is 1
Given Input Data is 87, 641, 767, 640
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 87 is 3 x 29
Prime Factorization of 641 is 641
Prime Factorization of 767 is 13 x 59
Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5
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(87, 641) = 55767
GCD(87, 641) = ( 87 x 641 ) / 55767
GCD(87, 641) = 55767 / 55767
GCD(87, 641) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 767
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 767) = 767
GCD(1, 767) = ( 1 x 767 ) / 767
GCD(1, 767) = 767 / 767
GCD(1, 767) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 640
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 640) = 640
GCD(1, 640) = ( 1 x 640 ) / 640
GCD(1, 640) = 640 / 640
GCD(1, 640) = 1
GCD of 87, 641, 767, 640 is 1
