So the greatest common factor 82,81,424 is 1.
Lets's calculate LCM of 103,694,474
2 | 103, 694, 474 |
103, 347, 237 |
∴ So the LCM of the given numbers is 2 x 103 x 347 x 237 = 16941234
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/16941234
Therefore, the GCF of Fractions 82/103,81/694,424/474 is 1/16941234
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 103,694,474 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(103,694,474) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(103,694,474) x common factors =1 x 2 = 2
LCM(103,694,474) = ( 103 × 694 × 474 ) / 2
LCM(103,694,474) = 33882468 / 2
LCM(103,694,474) = 16941234
