So the greatest common factor 96,42,68,98 is 2.
Lets's calculate LCM of 30,25,60,70
2 | 30, 25, 60, 70 |
3 | 15, 25, 30, 35 |
5 | 5, 25, 10, 35 |
1, 5, 2, 7 |
∴ So the LCM of the given numbers is 2 x 3 x 5 x 1 x 5 x 2 x 7 = 2100
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/2100
Therefore, the GCF of Fractions 96/30,42/25,68/60,98/70 is 2/2100
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 30,25,60,70 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(30,25,60,70) = 5
common factors(in case of two or more numbers have common factors) = 300
GCF(30,25,60,70) x common factors =5 x 300 = 1500
LCM(30,25,60,70) = ( 30 × 25 × 60 × 70 ) / 1500
LCM(30,25,60,70) = 3150000 / 1500
LCM(30,25,60,70) = 2100
