:1,3,17,51
Now, list down the factors of 783
:1,3,9,27,29,87,261,783
Now, list down the factors of 642
:1,2,3,6,107,214,321,642
Greatest Common Factor
We found the factors 51,783,642 . The biggest common factor number is the GCF number.
So the greatest common factor 51,783,642 is 3.
Lets's calculate LCM of 47,14,648
2 | 47, 14, 648 |
47, 7, 324 |
∴ So the LCM of the given numbers is 2 x 47 x 7 x 324 = 213192
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/213192
Therefore, the GCF of Fractions 51/47,783/14,642/648 is 3/213192
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 47,14,648 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(47,14,648) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(47,14,648) x common factors =1 x 2 = 2
LCM(47,14,648) = ( 47 × 14 × 648 ) / 2
LCM(47,14,648) = 426384 / 2
LCM(47,14,648) = 213192
