So the greatest common factor 54,415,411 is 1.
Lets's calculate LCM of 788,272,312
2 | 788, 272, 312 |
2 | 394, 136, 156 |
2 | 197, 68, 78 |
197, 34, 39 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 197 x 34 x 39 = 2089776
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2089776
Therefore, the GCF of Fractions 54/788,415/272,411/312 is 1/2089776
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 788,272,312 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(788,272,312) = 4
common factors(in case of two or more numbers have common factors) = 8
GCF(788,272,312) x common factors =4 x 8 = 32
LCM(788,272,312) = ( 788 × 272 × 312 ) / 32
LCM(788,272,312) = 66872832 / 32
LCM(788,272,312) = 2089776
