Greatest Common Factor
We found the factors 82,45,49,87 . The biggest common factor number is the GCF number.
So the greatest common factor 82,45,49,87 is 1.
Lets's calculate LCM of 11,88,52,80
2 | 11, 88, 52, 80 |
2 | 11, 44, 26, 40 |
2 | 11, 22, 13, 20 |
11 | 11, 11, 13, 10 |
1, 1, 13, 10 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 11 x 1 x 1 x 13 x 10 = 11440
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/11440
Therefore, the GCF of Fractions 82/11,45/88,49/52,87/80 is 1/11440
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 11,88,52,80 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(11,88,52,80) = 1
common factors(in case of two or more numbers have common factors) = 352
GCF(11,88,52,80) x common factors =1 x 352 = 352
LCM(11,88,52,80) = ( 11 × 88 × 52 × 80 ) / 352
LCM(11,88,52,80) = 4026880 / 352
LCM(11,88,52,80) = 11440
