So the greatest common factor 92,286,488 is 2.
Lets's calculate LCM of 12,28,643
2 | 12, 28, 643 |
2 | 6, 14, 643 |
3, 7, 643 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 7 x 643 = 54012
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/54012
Therefore, the GCF of Fractions 92/12,286/28,488/643 is 2/54012
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 12,28,643 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(12,28,643) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(12,28,643) x common factors =1 x 4 = 4
LCM(12,28,643) = ( 12 × 28 × 643 ) / 4
LCM(12,28,643) = 216048 / 4
LCM(12,28,643) = 54012
