Make use of GCD Calculator to determine the Greatest Common Divisor of 205, 765, 80, 554 i.e. 1 largest integer that divides all the numbers equally.
GCD of 205, 765, 80, 554 is 1
GCD(205, 765, 80, 554) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 205, 765, 80, 554 is 1
GCD(205, 765, 80, 554) = 1
Given Input numbers are 205, 765, 80, 554
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 277, 554
Greatest Common Divisior
We found the divisors of 205, 765, 80, 554 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 205, 765, 80, 554 is 1.
Therefore, GCD of numbers 205, 765, 80, 554 is 1
Given Input Data is 205, 765, 80, 554
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 205 is 5 x 41
Prime Factorization of 765 is 3 x 3 x 5 x 17
Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5
Prime Factorization of 554 is 2 x 277
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(205, 765) = 31365
GCD(205, 765) = ( 205 x 765 ) / 31365
GCD(205, 765) = 156825 / 31365
GCD(205, 765) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 80
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 80) = 80
GCD(5, 80) = ( 5 x 80 ) / 80
GCD(5, 80) = 400 / 80
GCD(5, 80) = 5
Step3:
Here we consider the GCD from the above i.e. 5 as first number and the next as 554
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 554) = 2770
GCD(5, 554) = ( 5 x 554 ) / 2770
GCD(5, 554) = 2770 / 2770
GCD(5, 554) = 1
GCD of 205, 765, 80, 554 is 1
