Lets's calculate LCM of 496,798
2 | 496, 798 |
248, 399 |
∴ So the LCM of the given numbers is 2 x 248 x 399 = 197904
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 103/197904
Therefore, the GCF of Fractions 618/496,515/798 is 103/197904
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 496,798 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(496,798) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(496,798) x common factors =2 x 1 = 2
LCM(496,798) = ( 496 × 798 ) / 2
LCM(496,798) = 395808 / 2
LCM(496,798) = 197904
