Lets's calculate LCM of 928,517,348
2 | 928, 517, 348 |
2 | 464, 517, 174 |
29 | 232, 517, 87 |
8, 517, 3 |
∴ So the LCM of the given numbers is 2 x 2 x 29 x 8 x 517 x 3 = 1439328
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/1439328
Therefore, the GCF of Fractions 78/928,48/517,519/348 is 3/1439328
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 928,517,348 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(928,517,348) = 1
common factors(in case of two or more numbers have common factors) = 116
GCF(928,517,348) x common factors =1 x 116 = 116
LCM(928,517,348) = ( 928 × 517 × 348 ) / 116
LCM(928,517,348) = 166962048 / 116
LCM(928,517,348) = 1439328
