Greatest Common Factor
We found the factors 30,647,309 . The biggest common factor number is the GCF number.
So the greatest common factor 30,647,309 is 1.
Lets's calculate LCM of 59,28,512
2 | 59, 28, 512 |
2 | 59, 14, 256 |
59, 7, 128 |
∴ So the LCM of the given numbers is 2 x 2 x 59 x 7 x 128 = 211456
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/211456
Therefore, the GCF of Fractions 30/59,647/28,309/512 is 1/211456
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 59,28,512 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(59,28,512) = 1
common factors(in case of two or more numbers have common factors) = 4
GCF(59,28,512) x common factors =1 x 4 = 4
LCM(59,28,512) = ( 59 × 28 × 512 ) / 4
LCM(59,28,512) = 845824 / 4
LCM(59,28,512) = 211456
