Lets's calculate GCF of 655,890
5 | 655, 890 |
131, 178 |
∴ So the GCF of the given numbers is 5 = 5
Now, list down the factors of 655
:1,5,131,655
Now, list down the factors of 890
:1,2,5,10,89,178,445,890
Greatest Common Factor
We found the factors 655,890 . The biggest common factor number is the GCF number.
So the greatest common factor 655,890 is 5.
Lets's calculate LCM of 815,220
5 | 815, 220 |
163, 44 |
∴ So the LCM of the given numbers is 5 x 163 x 44 = 35860
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/35860
Therefore, the GCF of Fractions 655/815,890/220 is 5/35860
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 815,220 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(815,220) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(815,220) x common factors =5 x 1 = 5
LCM(815,220) = ( 815 × 220 ) / 5
LCM(815,220) = 179300 / 5
LCM(815,220) = 35860
