Greatest Common Factor
We found the factors 804,830,905 . The biggest common factor number is the GCF number.
So the greatest common factor 804,830,905 is 1.
Lets's calculate LCM of 77,77,889
7 | 77, 77, 889 |
11 | 11, 11, 127 |
1, 1, 127 |
∴ So the LCM of the given numbers is 7 x 11 x 1 x 1 x 127 = 9779
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/9779
Therefore, the GCF of Fractions 804/77,830/77,905/889 is 1/9779
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 77,77,889 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,77,889) = 7
common factors(in case of two or more numbers have common factors) = 77
GCF(77,77,889) x common factors =7 x 77 = 539
LCM(77,77,889) = ( 77 × 77 × 889 ) / 539
LCM(77,77,889) = 5270881 / 539
LCM(77,77,889) = 9779
