Greatest Common Divisior
We found the divisors of 785, 982, 840, 436 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 785, 982, 840, 436 is 1.
Therefore, GCD of numbers 785, 982, 840, 436 is 1
Given Input Data is 785, 982, 840, 436
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 785 is 5 x 157
Prime Factorization of 982 is 2 x 491
Prime Factorization of 840 is 2 x 2 x 2 x 3 x 5 x 7
Prime Factorization of 436 is 2 x 2 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(785, 982) = 770870
GCD(785, 982) = ( 785 x 982 ) / 770870
GCD(785, 982) = 770870 / 770870
GCD(785, 982) = 1
Step2:
Here we consider the GCD from the above i.e. 1 as first number and the next as 840
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 840) = 840
GCD(1, 840) = ( 1 x 840 ) / 840
GCD(1, 840) = 840 / 840
GCD(1, 840) = 1
Step3:
Here we consider the GCD from the above i.e. 1 as first number and the next as 436
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(1, 436) = 436
GCD(1, 436) = ( 1 x 436 ) / 436
GCD(1, 436) = 436 / 436
GCD(1, 436) = 1
GCD of 785, 982, 840, 436 is 1
