3 | 660, 489 |
220, 163 |
∴ So the GCF of the given numbers is 3 = 3
Now, list down the factors of 660
:1,2,3,4,5,6,10,11,12,15,20,22,30,33,44,55,60,66,110,132,165,220,330,660
Now, list down the factors of 489
:1,3,163,489
Greatest Common Factor
We found the factors 660,489 . The biggest common factor number is the GCF number.
So the greatest common factor 660,489 is 3.
Lets's calculate LCM of 327,256
Given numbers has no common factors except 1. So, there LCM is their product i.e 83712
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/83712
Therefore, the GCF of Fractions 660/327,489/256 is 3/83712
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 327,256 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(327,256) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(327,256) x common factors =1 x 1 = 1
LCM(327,256) = ( 327 × 256 ) / 1
LCM(327,256) = 83712 / 1
LCM(327,256) = 83712
