So the greatest common factor 39,31,907 is 1.
Lets's calculate LCM of 219,315,749
3 | 219, 315, 749 |
7 | 73, 105, 749 |
73, 15, 107 |
∴ So the LCM of the given numbers is 3 x 7 x 73 x 15 x 107 = 2460465
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2460465
Therefore, the GCF of Fractions 39/219,31/315,907/749 is 1/2460465
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 219,315,749 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(219,315,749) = 1
common factors(in case of two or more numbers have common factors) = 21
GCF(219,315,749) x common factors =1 x 21 = 21
LCM(219,315,749) = ( 219 × 315 × 749 ) / 21
LCM(219,315,749) = 51669765 / 21
LCM(219,315,749) = 2460465
