So the greatest common factor 48,97,442 is 1.
Lets's calculate LCM of 78,362,830
2 | 78, 362, 830 |
39, 181, 415 |
∴ So the LCM of the given numbers is 2 x 39 x 181 x 415 = 5858970
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5858970
Therefore, the GCF of Fractions 48/78,97/362,442/830 is 1/5858970
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 78,362,830 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,362,830) = 2
common factors(in case of two or more numbers have common factors) = 2
GCF(78,362,830) x common factors =2 x 2 = 4
LCM(78,362,830) = ( 78 × 362 × 830 ) / 4
LCM(78,362,830) = 23435880 / 4
LCM(78,362,830) = 5858970
