1,2,7,13,14,26,91,182
Greatest Common Factor
We found the factors 21,75,43,182 . The biggest common factor number is the GCF number.
So the greatest common factor 21,75,43,182 is 1.
Lets's calculate LCM of 10,54,88,99
2 | 10, 54, 88, 99 |
3 | 5, 27, 44, 99 |
3 | 5, 9, 44, 33 |
11 | 5, 3, 44, 11 |
5, 3, 4, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 11 x 5 x 3 x 4 x 1 = 11880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/11880
Therefore, the GCF of Fractions 21/10,75/54,43/88,182/99 is 1/11880
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 10,54,88,99 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(10,54,88,99) = 1
common factors(in case of two or more numbers have common factors) = 396
GCF(10,54,88,99) x common factors =1 x 396 = 396
LCM(10,54,88,99) = ( 10 × 54 × 88 × 99 ) / 396
LCM(10,54,88,99) = 4704480 / 396
LCM(10,54,88,99) = 11880
