Greatest Common Factor
We found the factors 791,462 . The biggest common factor number is the GCF number.
So the greatest common factor 791,462 is 7.
Lets's calculate LCM of 72,5386
2 | 72, 5386 |
36, 2693 |
∴ So the LCM of the given numbers is 2 x 36 x 2693 = 193896
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/193896
Therefore, the GCF of Fractions 791/72,462/5386 is 7/193896
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 72,5386 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(72,5386) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(72,5386) x common factors =2 x 1 = 2
LCM(72,5386) = ( 72 × 5386 ) / 2
LCM(72,5386) = 387792 / 2
LCM(72,5386) = 193896
