So the greatest common factor 82,152,380 is 2.
Lets's calculate LCM of 87,30,391
3 | 87, 30, 391 |
29, 10, 391 |
∴ So the LCM of the given numbers is 3 x 29 x 10 x 391 = 340170
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/340170
Therefore, the GCF of Fractions 82/87,152/30,380/391 is 2/340170
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 87,30,391 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(87,30,391) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(87,30,391) x common factors =1 x 3 = 3
LCM(87,30,391) = ( 87 × 30 × 391 ) / 3
LCM(87,30,391) = 1020510 / 3
LCM(87,30,391) = 340170
