Greatest Common Divisior
We found the divisors of 369, 858, 765, 621 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 369, 858, 765, 621 is 3.
Therefore, GCD of numbers 369, 858, 765, 621 is 3
Given Input Data is 369, 858, 765, 621
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 369 is 3 x 3 x 41
Prime Factorization of 858 is 2 x 3 x 11 x 13
Prime Factorization of 765 is 3 x 3 x 5 x 17
Prime Factorization of 621 is 3 x 3 x 3 x 23
Highest common occurrences in the given inputs are 31
Multiplying them we get the GCD as 3
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(369, 858) = 105534
GCD(369, 858) = ( 369 x 858 ) / 105534
GCD(369, 858) = 316602 / 105534
GCD(369, 858) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 765
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 765) = 765
GCD(3, 765) = ( 3 x 765 ) / 765
GCD(3, 765) = 2295 / 765
GCD(3, 765) = 3
Step3:
Here we consider the GCD from the above i.e. 3 as first number and the next as 621
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 621) = 621
GCD(3, 621) = ( 3 x 621 ) / 621
GCD(3, 621) = 1863 / 621
GCD(3, 621) = 3
GCD of 369, 858, 765, 621 is 3
