Make use of GCD Calculator to determine the Greatest Common Divisor of 54, 90, 77 i.e. 1 largest integer that divides all the numbers equally.
GCD of 54, 90, 77 is 1
GCD(54, 90, 77) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 54, 90, 77 is 1
GCD(54, 90, 77) = 1
Given Input numbers are 54, 90, 77
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 54
List of positive integer divisors of 54 that divides 54 without a remainder.
1, 2, 3, 6, 9, 18, 27, 54
Divisors of 90
List of positive integer divisors of 90 that divides 90 without a remainder.
1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
Divisors of 77
List of positive integer divisors of 77 that divides 77 without a remainder.
1, 7, 11, 77
Greatest Common Divisior
We found the divisors of 54, 90, 77 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 54, 90, 77 is 1.
Therefore, GCD of numbers 54, 90, 77 is 1
Given Input Data is 54, 90, 77
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 54 is 2 x 3 x 3 x 3
Prime Factorization of 90 is 2 x 3 x 3 x 5
Prime Factorization of 77 is 7 x 11
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(54, 90) = 270
GCD(54, 90) = ( 54 x 90 ) / 270
GCD(54, 90) = 4860 / 270
GCD(54, 90) = 18
Step2:
Here we consider the GCD from the above i.e. 18 as first number and the next as 77
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(18, 77) = 1386
GCD(18, 77) = ( 18 x 77 ) / 1386
GCD(18, 77) = 1386 / 1386
GCD(18, 77) = 1
GCD of 54, 90, 77 is 1
