Greatest Common Factor
We found the factors 90,74,28,43 . The biggest common factor number is the GCF number.
So the greatest common factor 90,74,28,43 is 1.
Lets's calculate LCM of 24,98,64,16
2 | 24, 98, 64, 16 |
2 | 12, 49, 32, 8 |
2 | 6, 49, 16, 4 |
2 | 3, 49, 8, 2 |
3, 49, 4, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 3 x 49 x 4 x 1 = 9408
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9408
Therefore, the GCF of Fractions 90/24,74/98,28/64,43/16 is 1/9408
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 24,98,64,16 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(24,98,64,16) = 2
common factors(in case of two or more numbers have common factors) = 128
GCF(24,98,64,16) x common factors =2 x 128 = 256
LCM(24,98,64,16) = ( 24 × 98 × 64 × 16 ) / 256
LCM(24,98,64,16) = 2408448 / 256
LCM(24,98,64,16) = 9408
