Greatest Common Divisior
We found the divisors of 981, 944, 603, 780 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 981, 944, 603, 780 is 1.
Therefore, GCD of numbers 981, 944, 603, 780 is 1
Given Input Data is 981, 944, 603, 780
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 981 is 3 x 3 x 109
Prime Factorization of 944 is 2 x 2 x 2 x 2 x 59
Prime Factorization of 603 is 3 x 3 x 67
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(981, 944) = 926064
GCD(981, 944) = ( 981 x 944 ) / 926064
GCD(981, 944) = 926064 / 926064
GCD(981, 944) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 603
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 603) = 603
GCD(1, 603) = ( 1 x 603 ) / 603
GCD(1, 603) = 603 / 603
GCD(1, 603) = 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 981, 944, 603, 780 is 1
