2 | 430, 830 |
5 | 215, 415 |
43, 83 |
∴ So the GCF of the given numbers is 2 x 5 = 10
Now, list down the factors of 430
:1,2,5,10,43,86,215,430
Now, list down the factors of 830
:1,2,5,10,83,166,415,830
Greatest Common Factor
We found the factors 430,830 . The biggest common factor number is the GCF number.
So the greatest common factor 430,830 is 10.
Lets's calculate LCM of 12,1977
3 | 12, 1977 |
4, 659 |
∴ So the LCM of the given numbers is 3 x 4 x 659 = 7908
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/7908
Therefore, the GCF of Fractions 430/12,830/1977 is 10/7908
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 12,1977 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(12,1977) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(12,1977) x common factors =3 x 1 = 3
LCM(12,1977) = ( 12 × 1977 ) / 3
LCM(12,1977) = 23724 / 3
LCM(12,1977) = 7908
