So the greatest common factor 140,562,744 is 2.
Lets's calculate LCM of 38,98,42
2 | 38, 98, 42 |
7 | 19, 49, 21 |
19, 7, 3 |
∴ So the LCM of the given numbers is 2 x 7 x 19 x 7 x 3 = 5586
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/5586
Therefore, the GCF of Fractions 140/38,562/98,744/42 is 2/5586
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 38,98,42 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(38,98,42) = 2
common factors(in case of two or more numbers have common factors) = 14
GCF(38,98,42) x common factors =2 x 14 = 28
LCM(38,98,42) = ( 38 × 98 × 42 ) / 28
LCM(38,98,42) = 156408 / 28
LCM(38,98,42) = 5586
