Lets's calculate LCM of 174,798
2 | 174, 798 |
3 | 87, 399 |
29, 133 |
∴ So the LCM of the given numbers is 2 x 3 x 29 x 133 = 23142
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/23142
Therefore, the GCF of Fractions 985/174,678/798 is 1/23142
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 174,798 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(174,798) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(174,798) x common factors =6 x 1 = 6
LCM(174,798) = ( 174 × 798 ) / 6
LCM(174,798) = 138852 / 6
LCM(174,798) = 23142
