Greatest Common Divisior
We found the divisors of 685, 868, 672, 278 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 685, 868, 672, 278 is 1.
Therefore, GCD of numbers 685, 868, 672, 278 is 1
Given Input Data is 685, 868, 672, 278
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 685 is 5 x 137
Prime Factorization of 868 is 2 x 2 x 7 x 31
Prime Factorization of 672 is 2 x 2 x 2 x 2 x 2 x 3 x 7
Prime Factorization of 278 is 2 x 139
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(685, 868) = 594580
GCD(685, 868) = ( 685 x 868 ) / 594580
GCD(685, 868) = 594580 / 594580
GCD(685, 868) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 672
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 672) = 672
GCD(1, 672) = ( 1 x 672 ) / 672
GCD(1, 672) = 672 / 672
GCD(1, 672) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 278
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 278) = 278
GCD(1, 278) = ( 1 x 278 ) / 278
GCD(1, 278) = 278 / 278
GCD(1, 278) = 1
GCD of 685, 868, 672, 278 is 1
