Greatest Common Divisior
We found the divisors of 781, 170, 822, 407 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 781, 170, 822, 407 is 1.
Therefore, GCD of numbers 781, 170, 822, 407 is 1
Given Input Data is 781, 170, 822, 407
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 781 is 11 x 71
Prime Factorization of 170 is 2 x 5 x 17
Prime Factorization of 822 is 2 x 3 x 137
Prime Factorization of 407 is 11 x 37
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(781, 170) = 132770
GCD(781, 170) = ( 781 x 170 ) / 132770
GCD(781, 170) = 132770 / 132770
GCD(781, 170) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 822
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 822) = 822
GCD(1, 822) = ( 1 x 822 ) / 822
GCD(1, 822) = 822 / 822
GCD(1, 822) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 407
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 407) = 407
GCD(1, 407) = ( 1 x 407 ) / 407
GCD(1, 407) = 407 / 407
GCD(1, 407) = 1
GCD of 781, 170, 822, 407 is 1
