So the greatest common factor 7228,7120 is 4.
Lets's calculate LCM of 840,2540
2 | 840, 2540 |
2 | 420, 1270 |
5 | 210, 635 |
42, 127 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 42 x 127 = 106680
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/106680
Therefore, the GCF of Fractions 7228/840,7120/2540 is 4/106680
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 840,2540 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(840,2540) = 20
common factors(in case of two or more numbers have common factors) = 1
GCF(840,2540) x common factors =20 x 1 = 20
LCM(840,2540) = ( 840 × 2540 ) / 20
LCM(840,2540) = 2133600 / 20
LCM(840,2540) = 106680
