5 | 110, 225 |
22, 45 |
∴ So the GCF of the given numbers is 2 x 2 x 5 = 20
Now, list down the factors of 440
:1,2,4,5,8,10,11,20,22,40,44,55,88,110,220,440
Now, list down the factors of 900
:1,2,3,4,5,6,9,10,12,15,18,20,25,30,36,45,50,60,75,90,100,150,180,225,300,450,900
Greatest Common Factor
We found the factors 440,900 . The biggest common factor number is the GCF number.
So the greatest common factor 440,900 is 20.
Lets's calculate LCM of 955,730
5 | 955, 730 |
191, 146 |
∴ So the LCM of the given numbers is 5 x 191 x 146 = 139430
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 20/139430
Therefore, the GCF of Fractions 440/955,900/730 is 20/139430
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 955,730 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(955,730) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(955,730) x common factors =5 x 1 = 5
LCM(955,730) = ( 955 × 730 ) / 5
LCM(955,730) = 697150 / 5
LCM(955,730) = 139430
