So the greatest common factor 69,38,891 is 1.
Lets's calculate LCM of 47,136,914
2 | 47, 136, 914 |
47, 68, 457 |
∴ So the LCM of the given numbers is 2 x 47 x 68 x 457 = 2921144
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2921144
Therefore, the GCF of Fractions 69/47,38/136,891/914 is 1/2921144
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 47,136,914 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(47,136,914) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(47,136,914) x common factors =1 x 2 = 2
LCM(47,136,914) = ( 47 × 136 × 914 ) / 2
LCM(47,136,914) = 5842288 / 2
LCM(47,136,914) = 2921144
