1,2,4,5,7,10,14,20,25,28,35,50,70,100,140,175,350,700
Greatest Common Factor
We found the factors 23,78,61,700 . The biggest common factor number is the GCF number.
So the greatest common factor 23,78,61,700 is 1.
Lets's calculate LCM of 40,34,39,54
2 | 40, 34, 39, 54 |
3 | 20, 17, 39, 27 |
20, 17, 13, 9 |
∴ So the LCM of the given numbers is 2 x 3 x 20 x 17 x 13 x 9 = 238680
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/238680
Therefore, the GCF of Fractions 23/40,78/34,61/39,700/54 is 1/238680
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 40,34,39,54 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(40,34,39,54) = 1
common factors(in case of two or more numbers have common factors) = 12
GCF(40,34,39,54) x common factors =1 x 12 = 12
LCM(40,34,39,54) = ( 40 × 34 × 39 × 54 ) / 12
LCM(40,34,39,54) = 2864160 / 12
LCM(40,34,39,54) = 238680
