Lets's calculate LCM of 930,173,519
3 | 930, 173, 519 |
173 | 310, 173, 173 |
310, 1, 1 |
∴ So the LCM of the given numbers is 3 x 173 x 310 x 1 x 1 = 160890
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/160890
Therefore, the GCF of Fractions 138/930,786/173,742/519 is 2/160890
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 930,173,519 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(930,173,519) = 1
common factors(in case of two or more numbers have common factors) = 519
GCF(930,173,519) x common factors =1 x 519 = 519
LCM(930,173,519) = ( 930 × 173 × 519 ) / 519
LCM(930,173,519) = 83501910 / 519
LCM(930,173,519) = 160890
