Greatest Common Divisior
We found the divisors of 436, 885, 128, 646 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 436, 885, 128, 646 is 1.
Therefore, GCD of numbers 436, 885, 128, 646 is 1
Given Input Data is 436, 885, 128, 646
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 436 is 2 x 2 x 109
Prime Factorization of 885 is 3 x 5 x 59
Prime Factorization of 128 is 2 x 2 x 2 x 2 x 2 x 2 x 2
Prime Factorization of 646 is 2 x 17 x 19
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(436, 885) = 385860
GCD(436, 885) = ( 436 x 885 ) / 385860
GCD(436, 885) = 385860 / 385860
GCD(436, 885) = 1
Step2:
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
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 646
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
GCD(1, 646) = 646 / 646
GCD(1, 646) = 1
GCD of 436, 885, 128, 646 is 1
