1, 11, 71, 781
Greatest Common Divisior
We found the divisors of 206, 664, 545, 781 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 206, 664, 545, 781 is 1.
Therefore, GCD of numbers 206, 664, 545, 781 is 1
Given Input Data is 206, 664, 545, 781
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 206 is 2 x 103
Prime Factorization of 664 is 2 x 2 x 2 x 83
Prime Factorization of 545 is 5 x 109
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(206, 664) = 68392
GCD(206, 664) = ( 206 x 664 ) / 68392
GCD(206, 664) = 136784 / 68392
GCD(206, 664) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 545
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 545) = 1090
GCD(2, 545) = ( 2 x 545 ) / 1090
GCD(2, 545) = 1090 / 1090
GCD(2, 545) = 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 206, 664, 545, 781 is 1
