Make use of GCD Calculator to determine the Greatest Common Divisor of 57, 79, 98, 42 i.e. 1 largest integer that divides all the numbers equally.
GCD of 57, 79, 98, 42 is 1
GCD(57, 79, 98, 42) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 57, 79, 98, 42 is 1
GCD(57, 79, 98, 42) = 1
Given Input numbers are 57, 79, 98, 42
To find the GCD of numbers using factoring list out all the divisors of each number

1, 2, 7, 14, 49, 98
Divisors of 42
List of positive integer divisors of 42 that divides 42 without a remainder.
1, 2, 3, 6, 7, 14, 21, 42
Greatest Common Divisior
We found the divisors of 57, 79, 98, 42 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 57, 79, 98, 42 is 1.
Therefore, GCD of numbers 57, 79, 98, 42 is 1
Given Input Data is 57, 79, 98, 42
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 57 is 3 x 19
Prime Factorization of 79 is 79
Prime Factorization of 98 is 2 x 7 x 7
Prime Factorization of 42 is 2 x 3 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(57, 79) = 4503
GCD(57, 79) = ( 57 x 79 ) / 4503
GCD(57, 79) = 4503 / 4503
GCD(57, 79) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 98
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 98) = 98
GCD(1, 98) = ( 1 x 98 ) / 98
GCD(1, 98) = 98 / 98
GCD(1, 98) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 42
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 42) = 42
GCD(1, 42) = ( 1 x 42 ) / 42
GCD(1, 42) = 42 / 42
GCD(1, 42) = 1
GCD of 57, 79, 98, 42 is 1
