Lets's calculate LCM of 186,820
2 | 186, 820 |
93, 410 |
∴ So the LCM of the given numbers is 2 x 93 x 410 = 76260
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/76260
Therefore, the GCF of Fractions 399/186,346/820 is 1/76260
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 186,820 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(186,820) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(186,820) x common factors =2 x 1 = 2
LCM(186,820) = ( 186 × 820 ) / 2
LCM(186,820) = 152520 / 2
LCM(186,820) = 76260
