Lets's calculate LCM of 684,712
2 | 684, 712 |
2 | 342, 356 |
171, 178 |
∴ So the LCM of the given numbers is 2 x 2 x 171 x 178 = 121752
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/121752
Therefore, the GCF of Fractions 858/684,4101/712 is 3/121752
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 684,712 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(684,712) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(684,712) x common factors =4 x 1 = 4
LCM(684,712) = ( 684 × 712 ) / 4
LCM(684,712) = 487008 / 4
LCM(684,712) = 121752
