Lets's calculate LCM of 928,378
2 | 928, 378 |
464, 189 |
∴ So the LCM of the given numbers is 2 x 464 x 189 = 175392
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 23/175392
Therefore, the GCF of Fractions 874/928,621/378 is 23/175392
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 928,378 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(928,378) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(928,378) x common factors =2 x 1 = 2
LCM(928,378) = ( 928 × 378 ) / 2
LCM(928,378) = 350784 / 2
LCM(928,378) = 175392
