Make use of GCD Calculator to determine the Greatest Common Divisor of 991, 865, 71, 545 i.e. 1 largest integer that divides all the numbers equally.
GCD of 991, 865, 71, 545 is 1
GCD(991, 865, 71, 545) = 1
Ex: 10, 15, 20 (or) 24, 48, 96,45 (or) 78902, 89765, 12345
GCD of numbers 991, 865, 71, 545 is 1
GCD(991, 865, 71, 545) = 1
Given Input numbers are 991, 865, 71, 545
To find the GCD of numbers using factoring list out all the divisors of each number

1, 5, 109, 545
Greatest Common Divisior
We found the divisors of 991, 865, 71, 545 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 991, 865, 71, 545 is 1.
Therefore, GCD of numbers 991, 865, 71, 545 is 1
Given Input Data is 991, 865, 71, 545
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 991 is 991
Prime Factorization of 865 is 5 x 173
Prime Factorization of 71 is 71
Prime Factorization of 545 is 5 x 109
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(991, 865) = 857215
GCD(991, 865) = ( 991 x 865 ) / 857215
GCD(991, 865) = 857215 / 857215
GCD(991, 865) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 71
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 71) = 71
GCD(1, 71) = ( 1 x 71 ) / 71
GCD(1, 71) = 71 / 71
GCD(1, 71) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 545
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 545) = 545
GCD(1, 545) = ( 1 x 545 ) / 545
GCD(1, 545) = 545 / 545
GCD(1, 545) = 1
GCD of 991, 865, 71, 545 is 1
