We found the factors 351,4206 . The biggest common factor number is the GCF number.
So the greatest common factor 351,4206 is 3.
Lets's calculate LCM of 968,248
2 | 968, 248 |
2 | 484, 124 |
2 | 242, 62 |
121, 31 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 121 x 31 = 30008
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/30008
Therefore, the GCF of Fractions 351/968,4206/248 is 3/30008
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 968,248 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(968,248) = 8
common factors(in case of two or more numbers have common factors) = 1
GCF(968,248) x common factors =8 x 1 = 8
LCM(968,248) = ( 968 × 248 ) / 8
LCM(968,248) = 240064 / 8
LCM(968,248) = 30008
