So the greatest common factor 615,947 is 1.
Lets's calculate LCM of 207,393
3 | 207, 393 |
69, 131 |
∴ So the LCM of the given numbers is 3 x 69 x 131 = 27117
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/27117
Therefore, the GCF of Fractions 615/207,947/393 is 1/27117
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 207,393 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(207,393) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(207,393) x common factors =3 x 1 = 3
LCM(207,393) = ( 207 × 393 ) / 3
LCM(207,393) = 81351 / 3
LCM(207,393) = 27117
