1, 5, 179, 895
Greatest Common Divisior
We found the divisors of 690, 836, 812, 895 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 690, 836, 812, 895 is 1.
Therefore, GCD of numbers 690, 836, 812, 895 is 1
Given Input Data is 690, 836, 812, 895
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 690 is 2 x 3 x 5 x 23
Prime Factorization of 836 is 2 x 2 x 11 x 19
Prime Factorization of 812 is 2 x 2 x 7 x 29
Prime Factorization of 895 is 5 x 179
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(690, 836) = 288420
GCD(690, 836) = ( 690 x 836 ) / 288420
GCD(690, 836) = 576840 / 288420
GCD(690, 836) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 812
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 812) = 812
GCD(2, 812) = ( 2 x 812 ) / 812
GCD(2, 812) = 1624 / 812
GCD(2, 812) = 2
Step3:
Here we consider the GCD from the above i.e. 2 as first number and the next as 895
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 895) = 1790
GCD(2, 895) = ( 2 x 895 ) / 1790
GCD(2, 895) = 1790 / 1790
GCD(2, 895) = 1
GCD of 690, 836, 812, 895 is 1
