Make use of GCD Calculator to determine the Greatest Common Divisor of 178, 170, 43, 105 i.e. 1 largest integer that divides all the numbers equally.
GCD of 178, 170, 43, 105 is 1
GCD(178, 170, 43, 105) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 178, 170, 43, 105 is 1
GCD(178, 170, 43, 105) = 1
Given Input numbers are 178, 170, 43, 105
To find the GCD of numbers using factoring list out all the divisors of each number

1, 3, 5, 7, 15, 21, 35, 105
Greatest Common Divisior
We found the divisors of 178, 170, 43, 105 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 178, 170, 43, 105 is 1.
Therefore, GCD of numbers 178, 170, 43, 105 is 1
Given Input Data is 178, 170, 43, 105
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 178 is 2 x 89
Prime Factorization of 170 is 2 x 5 x 17
Prime Factorization of 43 is 43
Prime Factorization of 105 is 3 x 5 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(178, 170) = 15130
GCD(178, 170) = ( 178 x 170 ) / 15130
GCD(178, 170) = 30260 / 15130
GCD(178, 170) = 2
Step2:
Here we consider the GCD from the above i.e. 2 as first number and the next as 43
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(2, 43) = 86
GCD(2, 43) = ( 2 x 43 ) / 86
GCD(2, 43) = 86 / 86
GCD(2, 43) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 105
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 105) = 105
GCD(1, 105) = ( 1 x 105 ) / 105
GCD(1, 105) = 105 / 105
GCD(1, 105) = 1
GCD of 178, 170, 43, 105 is 1
