Lets's calculate LCM of 345,780
3 | 345, 780 |
5 | 115, 260 |
23, 52 |
∴ So the LCM of the given numbers is 3 x 5 x 23 x 52 = 17940
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/17940
Therefore, the GCF of Fractions 679/345,778/780 is 1/17940
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 345,780 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(345,780) = 15
common factors(in case of two or more numbers have common factors) = 1
GCF(345,780) x common factors =15 x 1 = 15
LCM(345,780) = ( 345 × 780 ) / 15
LCM(345,780) = 269100 / 15
LCM(345,780) = 17940
