Greatest Common Factor
We found the factors 23,74,79,47 . The biggest common factor number is the GCF number.
So the greatest common factor 23,74,79,47 is 1.
Lets's calculate LCM of 65,16,65,512
2 | 65, 16, 65, 512 |
2 | 65, 8, 65, 256 |
2 | 65, 4, 65, 128 |
2 | 65, 2, 65, 64 |
5 | 65, 1, 65, 32 |
13 | 13, 1, 13, 32 |
1, 1, 1, 32 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 2 x 5 x 13 x 1 x 1 x 1 x 32 = 33280
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/33280
Therefore, the GCF of Fractions 23/65,74/16,79/65,47/512 is 1/33280
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 65,16,65,512 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(65,16,65,512) = 1
common factors(in case of two or more numbers have common factors) = 1040
GCF(65,16,65,512) x common factors =1 x 1040 = 1040
LCM(65,16,65,512) = ( 65 × 16 × 65 × 512 ) / 1040
LCM(65,16,65,512) = 34611200 / 1040
LCM(65,16,65,512) = 33280
