Lets's calculate LCM of 854,392
2 | 854, 392 |
7 | 427, 196 |
61, 28 |
∴ So the LCM of the given numbers is 2 x 7 x 61 x 28 = 23912
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/23912
Therefore, the GCF of Fractions 319/854,378/392 is 1/23912
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 854,392 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(854,392) = 14
common factors(in case of two or more numbers have common factors) = 1
GCF(854,392) x common factors =14 x 1 = 14
LCM(854,392) = ( 854 × 392 ) / 14
LCM(854,392) = 334768 / 14
LCM(854,392) = 23912
