So the greatest common factor 42,337,806 is 1.
Lets's calculate LCM of 28,91,695
7 | 28, 91, 695 |
4, 13, 695 |
∴ So the LCM of the given numbers is 7 x 4 x 13 x 695 = 252980
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/252980
Therefore, the GCF of Fractions 42/28,337/91,806/695 is 1/252980
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 28,91,695 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,91,695) = 1
common factors(in case of two or more numbers have common factors) = 7
GCF(28,91,695) x common factors =1 x 7 = 7
LCM(28,91,695) = ( 28 × 91 × 695 ) / 7
LCM(28,91,695) = 1770860 / 7
LCM(28,91,695) = 252980
