So the greatest common factor 425,880 is 5.
Lets's calculate LCM of 27,639
3 | 27, 639 |
3 | 9, 213 |
3, 71 |
∴ So the LCM of the given numbers is 3 x 3 x 3 x 71 = 1917
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/1917
Therefore, the GCF of Fractions 425/27,880/639 is 5/1917
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 27,639 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(27,639) = 9
common factors(in case of two or more numbers have common factors) = 1
GCF(27,639) x common factors =9 x 1 = 9
LCM(27,639) = ( 27 × 639 ) / 9
LCM(27,639) = 17253 / 9
LCM(27,639) = 1917
