Greatest Common Divisior
We found the divisors of 578, 490, 278, 820 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 578, 490, 278, 820 is 2.
Therefore, GCD of numbers 578, 490, 278, 820 is 2
Given Input Data is 578, 490, 278, 820
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 578 is 2 x 17 x 17
Prime Factorization of 490 is 2 x 5 x 7 x 7
Prime Factorization of 278 is 2 x 139
Prime Factorization of 820 is 2 x 2 x 5 x 41
Highest common occurrences in the given inputs are 21
Multiplying them we get the GCD as 2
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(578, 490) = 141610
GCD(578, 490) = ( 578 x 490 ) / 141610
GCD(578, 490) = 283220 / 141610
GCD(578, 490) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 278
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 278) = 278
GCD(2, 278) = ( 2 x 278 ) / 278
GCD(2, 278) = 556 / 278
GCD(2, 278) = 2
Step3:
Here we consider the GCD from the above i.e. 2 as first number and the next as 820
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 820) = 820
GCD(2, 820) = ( 2 x 820 ) / 820
GCD(2, 820) = 1640 / 820
GCD(2, 820) = 2
GCD of 578, 490, 278, 820 is 2
