:1,3,5,9,15,25,45,75,225
Now, list down the factors of 720
:1,2,3,4,5,6,8,9,10,12,15,16,18,20,24,30,36,40,45,48,60,72,80,90,120,144,180,240,360,720
Greatest Common Factor
We found the factors 225,720 . The biggest common factor number is the GCF number.
So the greatest common factor 225,720 is 45.
Lets's calculate LCM of 342,410
2 | 342, 410 |
171, 205 |
∴ So the LCM of the given numbers is 2 x 171 x 205 = 70110
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 45/70110
Therefore, the GCF of Fractions 225/342,720/410 is 45/70110
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 342,410 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(342,410) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(342,410) x common factors =2 x 1 = 2
LCM(342,410) = ( 342 × 410 ) / 2
LCM(342,410) = 140220 / 2
LCM(342,410) = 70110
