So the greatest common factor 80,676,440 is 4.
Lets's calculate LCM of 54,38,988
2 | 54, 38, 988 |
19 | 27, 19, 494 |
27, 1, 26 |
∴ So the LCM of the given numbers is 2 x 19 x 27 x 1 x 26 = 26676
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/26676
Therefore, the GCF of Fractions 80/54,676/38,440/988 is 4/26676
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 54,38,988 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(54,38,988) = 2
common factors(in case of two or more numbers have common factors) = 38
GCF(54,38,988) x common factors =2 x 38 = 76
LCM(54,38,988) = ( 54 × 38 × 988 ) / 76
LCM(54,38,988) = 2027376 / 76
LCM(54,38,988) = 26676
