Greatest Common Divisior
We found the divisors of 769, 862, 634, 640 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 769, 862, 634, 640 is 1.
Therefore, GCD of numbers 769, 862, 634, 640 is 1
Given Input Data is 769, 862, 634, 640
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 769 is 769
Prime Factorization of 862 is 2 x 431
Prime Factorization of 634 is 2 x 317
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(769, 862) = 662878
GCD(769, 862) = ( 769 x 862 ) / 662878
GCD(769, 862) = 662878 / 662878
GCD(769, 862) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 634
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 634) = 634
GCD(1, 634) = ( 1 x 634 ) / 634
GCD(1, 634) = 634 / 634
GCD(1, 634) = 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 769, 862, 634, 640 is 1
