So the greatest common factor 98,866,387 is 1.
Lets's calculate LCM of 28,49,343
7 | 28, 49, 343 |
7 | 4, 7, 49 |
4, 1, 7 |
∴ So the LCM of the given numbers is 7 x 7 x 4 x 1 x 7 = 1372
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1372
Therefore, the GCF of Fractions 98/28,866/49,387/343 is 1/1372
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 28,49,343 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(28,49,343) = 7
common factors(in case of two or more numbers have common factors) = 49
GCF(28,49,343) x common factors =7 x 49 = 343
LCM(28,49,343) = ( 28 × 49 × 343 ) / 343
LCM(28,49,343) = 470596 / 343
LCM(28,49,343) = 1372
