Greatest Common Divisior
We found the divisors of 861, 885, 46, 128 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 861, 885, 46, 128 is 1.
Therefore, GCD of numbers 861, 885, 46, 128 is 1
Given Input Data is 861, 885, 46, 128
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 861 is 3 x 7 x 41
Prime Factorization of 885 is 3 x 5 x 59
Prime Factorization of 46 is 2 x 23
Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2
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(861, 885) = 253995
GCD(861, 885) = ( 861 x 885 ) / 253995
GCD(861, 885) = 761985 / 253995
GCD(861, 885) = 3
Step2:
Here we consider the GCD from the above i.e. 3 as first number and the next as 46
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(3, 46) = 138
GCD(3, 46) = ( 3 x 46 ) / 138
GCD(3, 46) = 138 / 138
GCD(3, 46) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 128
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
GCD(1, 128) = 128 / 128
GCD(1, 128) = 1
GCD of 861, 885, 46, 128 is 1
