1, 2, 197, 394
Greatest Common Divisior
We found the divisors of 77, 551, 436, 394 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 77, 551, 436, 394 is 1.
Therefore, GCD of numbers 77, 551, 436, 394 is 1
Given Input Data is 77, 551, 436, 394
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 77 is 7 x 11
Prime Factorization of 551 is 19 x 29
Prime Factorization of 436 is 2 x 2 x 109
Prime Factorization of 394 is 2 x 197
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(77, 551) = 42427
GCD(77, 551) = ( 77 x 551 ) / 42427
GCD(77, 551) = 42427 / 42427
GCD(77, 551) = 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 394
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 394) = 394
GCD(1, 394) = ( 1 x 394 ) / 394
GCD(1, 394) = 394 / 394
GCD(1, 394) = 1
GCD of 77, 551, 436, 394 is 1
