Greatest Common Factor
We found the factors 16,74,94,16 . The biggest common factor number is the GCF number.
So the greatest common factor 16,74,94,16 is 2.
Lets's calculate LCM of 16,80,56,243
2 | 16, 80, 56, 243 |
2 | 8, 40, 28, 243 |
2 | 4, 20, 14, 243 |
2 | 2, 10, 7, 243 |
1, 5, 7, 243 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 1 x 5 x 7 x 243 = 136080
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/136080
Therefore, the GCF of Fractions 16/16,74/80,94/56,16/243 is 2/136080
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 16,80,56,243 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(16,80,56,243) = 1
common factors(in case of two or more numbers have common factors) = 128
GCF(16,80,56,243) x common factors =1 x 128 = 128
LCM(16,80,56,243) = ( 16 × 80 × 56 × 243 ) / 128
LCM(16,80,56,243) = 17418240 / 128
LCM(16,80,56,243) = 136080
