So the greatest common factor 36,58,398 is 2.
Lets's calculate LCM of 34,78,51
2 | 34, 78, 51 |
3 | 17, 39, 51 |
17 | 17, 13, 17 |
1, 13, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 17 x 1 x 13 x 1 = 1326
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/1326
Therefore, the GCF of Fractions 36/34,58/78,398/51 is 2/1326
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 34,78,51 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(34,78,51) = 1
common factors(in case of two or more numbers have common factors) = 102
GCF(34,78,51) x common factors =1 x 102 = 102
LCM(34,78,51) = ( 34 × 78 × 51 ) / 102
LCM(34,78,51) = 135252 / 102
LCM(34,78,51) = 1326
