So the greatest common factor 280,785 is 5.
Lets's calculate LCM of 30,3126
2 | 30, 3126 |
3 | 15, 1563 |
5, 521 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 521 = 15630
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/15630
Therefore, the GCF of Fractions 280/30,785/3126 is 5/15630
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 30,3126 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,3126) = 6
common factors(in case of two or more numbers have common factors) = 1
GCF(30,3126) x common factors =6 x 1 = 6
LCM(30,3126) = ( 30 × 3126 ) / 6
LCM(30,3126) = 93780 / 6
LCM(30,3126) = 15630
