Greatest Common Divisior
We found the divisors of 577, 645, 436, 551 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 577, 645, 436, 551 is 1.
Therefore, GCD of numbers 577, 645, 436, 551 is 1
Given Input Data is 577, 645, 436, 551
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 577 is 577
Prime Factorization of 645 is 3 x 5 x 43
Prime Factorization of 436 is 2 x 2 x 109
Prime Factorization of 551 is 19 x 29
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(577, 645) = 372165
GCD(577, 645) = ( 577 x 645 ) / 372165
GCD(577, 645) = 372165 / 372165
GCD(577, 645) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 436
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 436) = 436
GCD(1, 436) = ( 1 x 436 ) / 436
GCD(1, 436) = 436 / 436
GCD(1, 436) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 551
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 551) = 551
GCD(1, 551) = ( 1 x 551 ) / 551
GCD(1, 551) = 551 / 551
GCD(1, 551) = 1
GCD of 577, 645, 436, 551 is 1
