So the greatest common factor 91,819,573 is 1.
Lets's calculate LCM of 78,49,488
2 | 78, 49, 488 |
39, 49, 244 |
∴ So the LCM of the given numbers is 2 x 39 x 49 x 244 = 932568
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/932568
Therefore, the GCF of Fractions 91/78,819/49,573/488 is 1/932568
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 78,49,488 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,49,488) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(78,49,488) x common factors =1 x 2 = 2
LCM(78,49,488) = ( 78 × 49 × 488 ) / 2
LCM(78,49,488) = 1865136 / 2
LCM(78,49,488) = 932568
