Lets's calculate GCF of 781,242
11 | 781, 242 |
71, 22 |
∴ So the GCF of the given numbers is 11 = 11
Now, list down the factors of 781
:1,11,71,781
Now, list down the factors of 242
:1,2,11,22,121,242
Greatest Common Factor
We found the factors 781,242 . The biggest common factor number is the GCF number.
So the greatest common factor 781,242 is 11.
Lets's calculate LCM of 430,444
2 | 430, 444 |
215, 222 |
∴ So the LCM of the given numbers is 2 x 215 x 222 = 95460
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 11/95460
Therefore, the GCF of Fractions 781/430,242/444 is 11/95460
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 430,444 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(430,444) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(430,444) x common factors =2 x 1 = 2
LCM(430,444) = ( 430 × 444 ) / 2
LCM(430,444) = 190920 / 2
LCM(430,444) = 95460
