Greatest Common Factor
We found the factors 3,44,89,93 . The biggest common factor number is the GCF number.
So the greatest common factor 3,44,89,93 is 1.
Lets's calculate LCM of 76,40,84,30
2 | 76, 40, 84, 30 |
2 | 38, 20, 42, 15 |
3 | 19, 10, 21, 15 |
5 | 19, 10, 7, 5 |
19, 2, 7, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 19 x 2 x 7 x 1 = 15960
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/15960
Therefore, the GCF of Fractions 3/76,44/40,89/84,93/30 is 1/15960
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 76,40,84,30 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(76,40,84,30) = 2
common factors(in case of two or more numbers have common factors) = 240
GCF(76,40,84,30) x common factors =2 x 240 = 480
LCM(76,40,84,30) = ( 76 × 40 × 84 × 30 ) / 480
LCM(76,40,84,30) = 7660800 / 480
LCM(76,40,84,30) = 15960
