So the greatest common factor 769,334,315 is 1.
Lets's calculate LCM of 98,42,86
2 | 98, 42, 86 |
7 | 49, 21, 43 |
7, 3, 43 |
∴ So the LCM of the given numbers is 2 x 7 x 7 x 3 x 43 = 12642
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/12642
Therefore, the GCF of Fractions 769/98,334/42,315/86 is 1/12642
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 98,42,86 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(98,42,86) = 2
common factors(in case of two or more numbers have common factors) = 14
GCF(98,42,86) x common factors =2 x 14 = 28
LCM(98,42,86) = ( 98 × 42 × 86 ) / 28
LCM(98,42,86) = 353976 / 28
LCM(98,42,86) = 12642
