Greatest Common Divisior
We found the divisors of 778, 785, 487, 195 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 778, 785, 487, 195 is 1.
Therefore, GCD of numbers 778, 785, 487, 195 is 1
Given Input Data is 778, 785, 487, 195
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 778 is 2 x 389
Prime Factorization of 785 is 5 x 157
Prime Factorization of 487 is 487
Prime Factorization of 195 is 3 x 5 x 13
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(778, 785) = 610730
GCD(778, 785) = ( 778 x 785 ) / 610730
GCD(778, 785) = 610730 / 610730
GCD(778, 785) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 487
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 487) = 487
GCD(1, 487) = ( 1 x 487 ) / 487
GCD(1, 487) = 487 / 487
GCD(1, 487) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 195
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 195) = 195
GCD(1, 195) = ( 1 x 195 ) / 195
GCD(1, 195) = 195 / 195
GCD(1, 195) = 1
GCD of 778, 785, 487, 195 is 1
