Greatest Common Factor
We found the factors 1,4,8,42 . The biggest common factor number is the GCF number.
So the greatest common factor 1,4,8,42 is 1.
Lets's calculate LCM of 56,22,99,882
2 | 56, 22, 99, 882 |
3 | 28, 11, 99, 441 |
3 | 28, 11, 33, 147 |
7 | 28, 11, 11, 49 |
11 | 4, 11, 11, 7 |
4, 1, 1, 7 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 7 x 11 x 4 x 1 x 1 x 7 = 38808
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/38808
Therefore, the GCF of Fractions 1/56,4/22,8/99,42/882 is 1/38808
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 56,22,99,882 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(56,22,99,882) = 1
common factors(in case of two or more numbers have common factors) = 2772
GCF(56,22,99,882) x common factors =1 x 2772 = 2772
LCM(56,22,99,882) = ( 56 × 22 × 99 × 882 ) / 2772
LCM(56,22,99,882) = 107575776 / 2772
LCM(56,22,99,882) = 38808
