We found the factors 130,2220 . The biggest common factor number is the GCF number.
So the greatest common factor 130,2220 is 10.
Lets's calculate LCM of 70,284
2 | 70, 284 |
35, 142 |
∴ So the LCM of the given numbers is 2 x 35 x 142 = 9940
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 10/9940
Therefore, the GCF of Fractions 130/70,2220/284 is 10/9940
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 70,284 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(70,284) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(70,284) x common factors =2 x 1 = 2
LCM(70,284) = ( 70 × 284 ) / 2
LCM(70,284) = 19880 / 2
LCM(70,284) = 9940
