Greatest Common Factor
We found the factors 308,670,939 . The biggest common factor number is the GCF number.
So the greatest common factor 308,670,939 is 1.
Lets's calculate LCM of 94,13,704
2 | 94, 13, 704 |
47, 13, 352 |
∴ So the LCM of the given numbers is 2 x 47 x 13 x 352 = 430144
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/430144
Therefore, the GCF of Fractions 308/94,670/13,939/704 is 1/430144
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 94,13,704 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(94,13,704) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(94,13,704) x common factors =1 x 2 = 2
LCM(94,13,704) = ( 94 × 13 × 704 ) / 2
LCM(94,13,704) = 860288 / 2
LCM(94,13,704) = 430144
