Greatest Common Factor
We found the factors 81,68,99,73 . The biggest common factor number is the GCF number.
So the greatest common factor 81,68,99,73 is 1.
Lets's calculate LCM of 31,28,67,946
2 | 31, 28, 67, 946 |
31, 14, 67, 473 |
∴ So the LCM of the given numbers is 2 x 31 x 14 x 67 x 473 = 27507788
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/27507788
Therefore, the GCF of Fractions 81/31,68/28,99/67,73/946 is 1/27507788
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 31,28,67,946 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(31,28,67,946) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(31,28,67,946) x common factors =1 x 2 = 2
LCM(31,28,67,946) = ( 31 × 28 × 67 × 946 ) / 2
LCM(31,28,67,946) = 55015576 / 2
LCM(31,28,67,946) = 27507788
