Lets's calculate LCM of 140,2142
2 | 140, 2142 |
7 | 70, 1071 |
10, 153 |
∴ So the LCM of the given numbers is 2 x 7 x 10 x 153 = 21420
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/21420
Therefore, the GCF of Fractions 2756/140,3987/2142 is 1/21420
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 140,2142 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(140,2142) = 14
common factors(in case of two or more numbers have common factors) = 1
GCF(140,2142) x common factors =14 x 1 = 14
LCM(140,2142) = ( 140 × 2142 ) / 14
LCM(140,2142) = 299880 / 14
LCM(140,2142) = 21420
