So the greatest common factor 464,155 is 1.
Lets's calculate LCM of 78,1235
13 | 78, 1235 |
6, 95 |
∴ So the LCM of the given numbers is 13 x 6 x 95 = 7410
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/7410
Therefore, the GCF of Fractions 464/78,155/1235 is 1/7410
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 78,1235 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,1235) = 13
common factors(in case of two or more numbers have common factors) = 1
GCF(78,1235) x common factors =13 x 1 = 13
LCM(78,1235) = ( 78 × 1235 ) / 13
LCM(78,1235) = 96330 / 13
LCM(78,1235) = 7410
