So the greatest common factor 712,648 is 8.
Lets's calculate LCM of 942,794
2 | 942, 794 |
471, 397 |
∴ So the LCM of the given numbers is 2 x 471 x 397 = 373974
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 8/373974
Therefore, the GCF of Fractions 712/942,648/794 is 8/373974
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 942,794 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(942,794) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(942,794) x common factors =2 x 1 = 2
LCM(942,794) = ( 942 × 794 ) / 2
LCM(942,794) = 747948 / 2
LCM(942,794) = 373974
