Lets's calculate LCM of 756,8880
2 | 756, 8880 |
2 | 378, 4440 |
3 | 189, 2220 |
63, 740 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 63 x 740 = 559440
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/559440
Therefore, the GCF of Fractions 1139/756,1689/8880 is 1/559440
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 756,8880 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(756,8880) = 12
common factors(in case of two or more numbers have common factors) = 1
GCF(756,8880) x common factors =12 x 1 = 12
LCM(756,8880) = ( 756 × 8880 ) / 12
LCM(756,8880) = 6713280 / 12
LCM(756,8880) = 559440
