:1,2,3,5,6,10,15,25,30,50,75,150
Greatest Common Factor
We found the factors 64,31,150 . The biggest common factor number is the GCF number.
So the greatest common factor 64,31,150 is 1.
Lets's calculate LCM of 81,946,210
2 | 81, 946, 210 |
3 | 81, 473, 105 |
27, 473, 35 |
∴ So the LCM of the given numbers is 2 x 3 x 27 x 473 x 35 = 2681910
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/2681910
Therefore, the GCF of Fractions 64/81,31/946,150/210 is 1/2681910
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 81,946,210 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(81,946,210) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(81,946,210) x common factors =1 x 6 = 6
LCM(81,946,210) = ( 81 × 946 × 210 ) / 6
LCM(81,946,210) = 16091460 / 6
LCM(81,946,210) = 2681910
