Greatest Common Factor
We found the factors 44,81,831 . The biggest common factor number is the GCF number.
So the greatest common factor 44,81,831 is 1.
Lets's calculate LCM of 768,755,685
5 | 768, 755, 685 |
768, 151, 137 |
∴ So the LCM of the given numbers is 5 x 768 x 151 x 137 = 79438080
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/79438080
Therefore, the GCF of Fractions 44/768,81/755,831/685 is 1/79438080
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 768,755,685 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(768,755,685) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(768,755,685) x common factors =1 x 5 = 5
LCM(768,755,685) = ( 768 × 755 × 685 ) / 5
LCM(768,755,685) = 397190400 / 5
LCM(768,755,685) = 79438080
