1, 3, 257, 771
Greatest Common Divisior
We found the divisors of 785, 862, 78, 771 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 785, 862, 78, 771 is 1.
Therefore, GCD of numbers 785, 862, 78, 771 is 1
Given Input Data is 785, 862, 78, 771
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 785 is 5 x 157
Prime Factorization of 862 is 2 x 431
Prime Factorization of 78 is 2 x 3 x 13
Prime Factorization of 771 is 3 x 257
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(785, 862) = 676670
GCD(785, 862) = ( 785 x 862 ) / 676670
GCD(785, 862) = 676670 / 676670
GCD(785, 862) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 78
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 78) = 78
GCD(1, 78) = ( 1 x 78 ) / 78
GCD(1, 78) = 78 / 78
GCD(1, 78) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 771
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 771) = 771
GCD(1, 771) = ( 1 x 771 ) / 771
GCD(1, 771) = 771 / 771
GCD(1, 771) = 1
GCD of 785, 862, 78, 771 is 1
