Make use of GCD Calculator to determine the Greatest Common Divisor of 191, 152, 66, 172 i.e. 1 largest integer that divides all the numbers equally.
GCD of 191, 152, 66, 172 is 1
GCD(191, 152, 66, 172) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 191, 152, 66, 172 is 1
GCD(191, 152, 66, 172) = 1
Given Input numbers are 191, 152, 66, 172
To find the GCD of numbers using factoring list out all the divisors of each number

Greatest Common Divisior
We found the divisors of 191, 152, 66, 172 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 191, 152, 66, 172 is 1.
Therefore, GCD of numbers 191, 152, 66, 172 is 1
Given Input Data is 191, 152, 66, 172
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 191 is 191
Prime Factorization of 152 is 2 x 2 x 2 x 19
Prime Factorization of 66 is 2 x 3 x 11
Prime Factorization of 172 is 2 x 2 x 43
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(191, 152) = 29032
GCD(191, 152) = ( 191 x 152 ) / 29032
GCD(191, 152) = 29032 / 29032
GCD(191, 152) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 66
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 66) = 66
GCD(1, 66) = ( 1 x 66 ) / 66
GCD(1, 66) = 66 / 66
GCD(1, 66) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 172
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 172) = 172
GCD(1, 172) = ( 1 x 172 ) / 172
GCD(1, 172) = 172 / 172
GCD(1, 172) = 1
GCD of 191, 152, 66, 172 is 1
