So the greatest common factor 60,67,987 is 1.
Lets's calculate LCM of 69,33,19
3 | 69, 33, 19 |
23, 11, 19 |
∴ So the LCM of the given numbers is 3 x 23 x 11 x 19 = 14421
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/14421
Therefore, the GCF of Fractions 60/69,67/33,987/19 is 1/14421
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 69,33,19 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(69,33,19) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(69,33,19) x common factors =1 x 3 = 3
LCM(69,33,19) = ( 69 × 33 × 19 ) / 3
LCM(69,33,19) = 43263 / 3
LCM(69,33,19) = 14421
