Greatest Common Factor
We found the factors 9,71,85,480 . The biggest common factor number is the GCF number.
So the greatest common factor 9,71,85,480 is 1.
Lets's calculate LCM of 42,48,136,460
2 | 42, 48, 136, 460 |
2 | 21, 24, 68, 230 |
2 | 21, 12, 34, 115 |
3 | 21, 6, 17, 115 |
7, 2, 17, 115 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 3 x 7 x 2 x 17 x 115 = 656880
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/656880
Therefore, the GCF of Fractions 9/42,71/48,85/136,480/460 is 1/656880
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 42,48,136,460 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(42,48,136,460) = 2
common factors(in case of two or more numbers have common factors) = 96
GCF(42,48,136,460) x common factors =2 x 96 = 192
LCM(42,48,136,460) = ( 42 × 48 × 136 × 460 ) / 192
LCM(42,48,136,460) = 126120960 / 192
LCM(42,48,136,460) = 656880
