Lets's calculate LCM of 381,638,820
2 | 381, 638, 820 |
381, 319, 410 |
∴ So the LCM of the given numbers is 2 x 381 x 319 x 410 = 99661980
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/99661980
Therefore, the GCF of Fractions 84/381,788/638,874/820 is 2/99661980
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 381,638,820 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(381,638,820) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(381,638,820) x common factors =1 x 2 = 2
LCM(381,638,820) = ( 381 × 638 × 820 ) / 2
LCM(381,638,820) = 199323960 / 2
LCM(381,638,820) = 99661980
