Make use of GCD Calculator to determine the Greatest Common Divisor of 49, 20, 53, 28 i.e. 1 largest integer that divides all the numbers equally.
GCD of 49, 20, 53, 28 is 1
GCD(49, 20, 53, 28) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 49, 20, 53, 28 is 1
GCD(49, 20, 53, 28) = 1
Given Input numbers are 49, 20, 53, 28
To find the GCD of numbers using factoring list out all the divisors of each number
Divisors of 49

1, 2, 4, 5, 10, 20
Divisors of 53
List of positive integer divisors of 53 that divides 53 without a remainder.
1, 53
Divisors of 28
List of positive integer divisors of 28 that divides 28 without a remainder.
1, 2, 4, 7, 14, 28
Greatest Common Divisior
We found the divisors of 49, 20, 53, 28 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 49, 20, 53, 28 is 1.
Therefore, GCD of numbers 49, 20, 53, 28 is 1
Given Input Data is 49, 20, 53, 28
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 49 is 7 x 7
Prime Factorization of 20 is 2 x 2 x 5
Prime Factorization of 53 is 53
Prime Factorization of 28 is 2 x 2 x 7
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(49, 20) = 980
GCD(49, 20) = ( 49 x 20 ) / 980
GCD(49, 20) = 980 / 980
GCD(49, 20) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 53
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 53) = 53
GCD(1, 53) = ( 1 x 53 ) / 53
GCD(1, 53) = 53 / 53
GCD(1, 53) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 28
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 28) = 28
GCD(1, 28) = ( 1 x 28 ) / 28
GCD(1, 28) = 28 / 28
GCD(1, 28) = 1
GCD of 49, 20, 53, 28 is 1
