Greatest Common Divisior
We found the divisors of 781, 845, 698, 575 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 781, 845, 698, 575 is 1.
Therefore, GCD of numbers 781, 845, 698, 575 is 1
Given Input Data is 781, 845, 698, 575
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 781 is 11 x 71
Prime Factorization of 845 is 5 x 13 x 13
Prime Factorization of 698 is 2 x 349
Prime Factorization of 575 is 5 x 5 x 23
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(781, 845) = 659945
GCD(781, 845) = ( 781 x 845 ) / 659945
GCD(781, 845) = 659945 / 659945
GCD(781, 845) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 698
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 698) = 698
GCD(1, 698) = ( 1 x 698 ) / 698
GCD(1, 698) = 698 / 698
GCD(1, 698) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 575
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 575) = 575
GCD(1, 575) = ( 1 x 575 ) / 575
GCD(1, 575) = 575 / 575
GCD(1, 575) = 1
GCD of 781, 845, 698, 575 is 1
