Greatest Common Factor
We found the factors 64,55,38,55,348,33,76,929,89,53 . The biggest common factor number is the GCF number.
So the greatest common factor 64,55,38,55,348,33,76,929,89,53 is 1.
Lets's calculate LCM of 9,8,7,1,9,8,8,3,2,2
2 | 9, 8, 7, 1, 9, 8, 8, 3, 2, 2 |
2 | 9, 4, 7, 1, 9, 4, 4, 3, 1, 1 |
2 | 9, 2, 7, 1, 9, 2, 2, 3, 1, 1 |
3 | 9, 1, 7, 1, 9, 1, 1, 3, 1, 1 |
3 | 1, 1, 7, 1, 3, 1, 1, 3, 1, 1 |
1, 1, 7, 1, 1, 1, 1, 1, 1, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 3 x 1 x 1 x 7 x 1 x 1 x 1 x 1 x 1 x 1 x 1 = 504
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/504
Therefore, the GCF of Fractions 64/9,55/8,38/7,55/1,348/9,33/8,76/8,929/3,89/2,53/2 is 1/504
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 9,8,7,1,9,8,8,3,2,2 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(9,8,7,1,9,8,8,3,2,2) = 1
common factors(in case of two or more numbers have common factors) = 6912
GCF(9,8,7,1,9,8,8,3,2,2) x common factors =1 x 6912 = 6912
LCM(9,8,7,1,9,8,8,3,2,2) = ( 9 × 8 × 7 × 1 × 9 × 8 × 8 × 3 × 2 × 2 ) / 6912
LCM(9,8,7,1,9,8,8,3,2,2) = 3483648 / 6912
LCM(9,8,7,1,9,8,8,3,2,2) = 504
