Greatest Common Divisior
We found the divisors of 985, 579, 859, 780 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 985, 579, 859, 780 is 1.
Therefore, GCD of numbers 985, 579, 859, 780 is 1
Given Input Data is 985, 579, 859, 780
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 985 is 5 x 197
Prime Factorization of 579 is 3 x 193
Prime Factorization of 859 is 859
Prime Factorization of 780 is 2 x 2 x 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(985, 579) = 570315
GCD(985, 579) = ( 985 x 579 ) / 570315
GCD(985, 579) = 570315 / 570315
GCD(985, 579) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 859
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 859) = 859
GCD(1, 859) = ( 1 x 859 ) / 859
GCD(1, 859) = 859 / 859
GCD(1, 859) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 780
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 780) = 780
GCD(1, 780) = ( 1 x 780 ) / 780
GCD(1, 780) = 780 / 780
GCD(1, 780) = 1
GCD of 985, 579, 859, 780 is 1
