Greatest Common Factor
We found the factors 41,96,21,74 . The biggest common factor number is the GCF number.
So the greatest common factor 41,96,21,74 is 1.
Lets's calculate LCM of 91,39,16,56
2 | 91, 39, 16, 56 |
2 | 91, 39, 8, 28 |
2 | 91, 39, 4, 14 |
7 | 91, 39, 2, 7 |
13 | 13, 39, 2, 1 |
1, 3, 2, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 7 x 13 x 1 x 3 x 2 x 1 = 4368
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/4368
Therefore, the GCF of Fractions 41/91,96/39,21/16,74/56 is 1/4368
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 91,39,16,56 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(91,39,16,56) = 1
common factors(in case of two or more numbers have common factors) = 728
GCF(91,39,16,56) x common factors =1 x 728 = 728
LCM(91,39,16,56) = ( 91 × 39 × 16 × 56 ) / 728
LCM(91,39,16,56) = 3179904 / 728
LCM(91,39,16,56) = 4368
