Greatest Common Factor
We found the factors 2,4,2,87 . The biggest common factor number is the GCF number.
So the greatest common factor 2,4,2,87 is 1.
Lets's calculate LCM of 81,61,17,927
3 | 81, 61, 17, 927 |
3 | 27, 61, 17, 309 |
9, 61, 17, 103 |
∴ So the LCM of the given numbers is 3 x 3 x 9 x 61 x 17 x 103 = 8651691
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/8651691
Therefore, the GCF of Fractions 2/81,4/61,2/17,87/927 is 1/8651691
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 81,61,17,927 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,61,17,927) = 1
common factors(in case of two or more numbers have common factors) = 9
GCF(81,61,17,927) x common factors =1 x 9 = 9
LCM(81,61,17,927) = ( 81 × 61 × 17 × 927 ) / 9
LCM(81,61,17,927) = 77865219 / 9
LCM(81,61,17,927) = 8651691
