So the greatest common factor 78,79,489 is 1.
Lets's calculate LCM of 100,318,910
2 | 100, 318, 910 |
5 | 50, 159, 455 |
10, 159, 91 |
∴ So the LCM of the given numbers is 2 x 5 x 10 x 159 x 91 = 1446900
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1446900
Therefore, the GCF of Fractions 78/100,79/318,489/910 is 1/1446900
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 100,318,910 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(100,318,910) = 2
common factors(in case of two or more numbers have common factors) = 10
GCF(100,318,910) x common factors =2 x 10 = 20
LCM(100,318,910) = ( 100 × 318 × 910 ) / 20
LCM(100,318,910) = 28938000 / 20
LCM(100,318,910) = 1446900
