Greatest Common Factor
We found the factors 52,97,91,89 . The biggest common factor number is the GCF number.
So the greatest common factor 52,97,91,89 is 1.
Lets's calculate LCM of 15,40,49,84
2 | 15, 40, 49, 84 |
2 | 15, 20, 49, 42 |
3 | 15, 10, 49, 21 |
5 | 5, 10, 49, 7 |
7 | 1, 2, 49, 7 |
1, 2, 1, 7 |
∴ So the LCM of the given numbers is 2 x 2 x 3 x 5 x 7 x 1 x 2 x 1 x 7 = 5880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/5880
Therefore, the GCF of Fractions 52/15,97/40,91/49,89/84 is 1/5880
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 15,40,49,84 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,40,49,84) = 1
common factors(in case of two or more numbers have common factors) = 420
GCF(15,40,49,84) x common factors =1 x 420 = 420
LCM(15,40,49,84) = ( 15 × 40 × 49 × 84 ) / 420
LCM(15,40,49,84) = 2469600 / 420
LCM(15,40,49,84) = 5880
