So the greatest common factor 1785,5970 is 15.
Lets's calculate LCM of 705,651
3 | 705, 651 |
235, 217 |
∴ So the LCM of the given numbers is 3 x 235 x 217 = 152985
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 15/152985
Therefore, the GCF of Fractions 1785/705,5970/651 is 15/152985
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 705,651 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(705,651) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(705,651) x common factors =3 x 1 = 3
LCM(705,651) = ( 705 × 651 ) / 3
LCM(705,651) = 458955 / 3
LCM(705,651) = 152985
