1,89
Greatest Common Factor
We found the factors 30,66,68,89 . The biggest common factor number is the GCF number.
So the greatest common factor 30,66,68,89 is 1.
Lets's calculate LCM of 71,63,84,135
3 | 71, 63, 84, 135 |
3 | 71, 21, 28, 45 |
7 | 71, 7, 28, 15 |
71, 1, 4, 15 |
∴ So the LCM of the given numbers is 3 x 3 x 7 x 71 x 1 x 4 x 15 = 268380
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/268380
Therefore, the GCF of Fractions 30/71,66/63,68/84,89/135 is 1/268380
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 71,63,84,135 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(71,63,84,135) = 1
common factors(in case of two or more numbers have common factors) = 189
GCF(71,63,84,135) x common factors =1 x 189 = 189
LCM(71,63,84,135) = ( 71 × 63 × 84 × 135 ) / 189
LCM(71,63,84,135) = 50723820 / 189
LCM(71,63,84,135) = 268380
