So the greatest common factor 69,518,513 is 1.
Lets's calculate LCM of 57,36,391
3 | 57, 36, 391 |
19, 12, 391 |
∴ So the LCM of the given numbers is 3 x 19 x 12 x 391 = 267444
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/267444
Therefore, the GCF of Fractions 69/57,518/36,513/391 is 1/267444
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 57,36,391 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(57,36,391) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(57,36,391) x common factors =1 x 3 = 3
LCM(57,36,391) = ( 57 × 36 × 391 ) / 3
LCM(57,36,391) = 802332 / 3
LCM(57,36,391) = 267444
