Greatest Common Factor
We found the factors 49,87,91,171 . The biggest common factor number is the GCF number.
So the greatest common factor 49,87,91,171 is 1.
Lets's calculate LCM of 94,78,78,24
2 | 94, 78, 78, 24 |
3 | 47, 39, 39, 12 |
13 | 47, 13, 13, 4 |
47, 1, 1, 4 |
∴ So the LCM of the given numbers is 2 x 3 x 13 x 47 x 1 x 1 x 4 = 14664
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/14664
Therefore, the GCF of Fractions 49/94,87/78,91/78,171/24 is 1/14664
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 94,78,78,24 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(94,78,78,24) = 2
common factors(in case of two or more numbers have common factors) = 468
GCF(94,78,78,24) x common factors =2 x 468 = 936
LCM(94,78,78,24) = ( 94 × 78 × 78 × 24 ) / 936
LCM(94,78,78,24) = 13725504 / 936
LCM(94,78,78,24) = 14664
