GCD of 305, 316, 78, 781 is 1
GCD(305, 316, 78, 781) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 305, 316, 78, 781 is 1
GCD(305, 316, 78, 781) = 1
Given Input numbers are 305, 316, 78, 781
To find the GCD of numbers using factoring list out all the divisors of each number

1, 11, 71, 781
Greatest Common Divisior
We found the divisors of 305, 316, 78, 781 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 305, 316, 78, 781 is 1.
Therefore, GCD of numbers 305, 316, 78, 781 is 1
Given Input Data is 305, 316, 78, 781
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 305 is 5 x 61
Prime Factorization of 316 is 2 x 2 x 79
Prime Factorization of 78 is 2 x 3 x 13
Prime Factorization of 781 is 11 x 71
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(305, 316) = 96380
GCD(305, 316) = ( 305 x 316 ) / 96380
GCD(305, 316) = 96380 / 96380
GCD(305, 316) = 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 781
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
GCD(1, 781) = 781 / 781
GCD(1, 781) = 1
GCD of 305, 316, 78, 781 is 1
