Lets's calculate GCF of 318,159
3 | 318, 159 |
53 | 106, 53 |
2, 1 |
∴ So the GCF of the given numbers is 3 x 53 = 159
Now, list down the factors of 318
:1,2,3,6,53,106,159,318
Now, list down the factors of 159
:1,3,53,159
Greatest Common Factor
We found the factors 318,159 . The biggest common factor number is the GCF number.
So the greatest common factor 318,159 is 159.
Lets's calculate LCM of 30,470
2 | 30, 470 |
5 | 15, 235 |
3, 47 |
∴ So the LCM of the given numbers is 2 x 5 x 3 x 47 = 1410
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 159/1410
Therefore, the GCF of Fractions 318/30,159/470 is 159/1410
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 30,470 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,470) = 10
common factors(in case of two or more numbers have common factors) = 1
GCF(30,470) x common factors =10 x 1 = 10
LCM(30,470) = ( 30 × 470 ) / 10
LCM(30,470) = 14100 / 10
LCM(30,470) = 1410
