So the greatest common factor 42,19,494 is 1.
Lets's calculate LCM of 99,59,699
3 | 99, 59, 699 |
33, 59, 233 |
∴ So the LCM of the given numbers is 3 x 33 x 59 x 233 = 1360953
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1360953
Therefore, the GCF of Fractions 42/99,19/59,494/699 is 1/1360953
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 99,59,699 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(99,59,699) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(99,59,699) x common factors =1 x 3 = 3
LCM(99,59,699) = ( 99 × 59 × 699 ) / 3
LCM(99,59,699) = 4082859 / 3
LCM(99,59,699) = 1360953
