Lets's calculate LCM of 112,686
2 | 112, 686 |
7 | 56, 343 |
8, 49 |
∴ So the LCM of the given numbers is 2 x 7 x 8 x 49 = 5488
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5488
Therefore, the GCF of Fractions 4207/112,4640/686 is 1/5488
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 112,686 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(112,686) = 14
common factors(in case of two or more numbers have common factors) = 1
GCF(112,686) x common factors =14 x 1 = 14
LCM(112,686) = ( 112 × 686 ) / 14
LCM(112,686) = 76832 / 14
LCM(112,686) = 5488
