1,2,3,4,6,8,12,16,24,32,48,64,96,128,192,256,384,768
Greatest Common Factor
We found the factors 49,12,768 . The biggest common factor number is the GCF number.
So the greatest common factor 49,12,768 is 1.
Lets's calculate LCM of 58,81,76
2 | 58, 81, 76 |
29, 81, 38 |
∴ So the LCM of the given numbers is 2 x 29 x 81 x 38 = 178524
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/178524
Therefore, the GCF of Fractions 49/58,12/81,768/76 is 1/178524
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 58,81,76 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(58,81,76) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(58,81,76) x common factors =1 x 2 = 2
LCM(58,81,76) = ( 58 × 81 × 76 ) / 2
LCM(58,81,76) = 357048 / 2
LCM(58,81,76) = 178524
