1,2,3,4,6,7,9,12,14,18,21,27,28,36,42,54,63,84,108,126,189,252,378,756
Greatest Common Factor
We found the factors 81,64,756 . The biggest common factor number is the GCF number.
So the greatest common factor 81,64,756 is 1.
Lets's calculate LCM of 913,308,889
7 | 913, 308, 889 |
11 | 913, 44, 127 |
83, 4, 127 |
∴ So the LCM of the given numbers is 7 x 11 x 83 x 4 x 127 = 3246628
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/3246628
Therefore, the GCF of Fractions 81/913,64/308,756/889 is 1/3246628
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 913,308,889 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(913,308,889) = 1
common factors(in case of two or more numbers have common factors) = 77
GCF(913,308,889) x common factors =1 x 77 = 77
LCM(913,308,889) = ( 913 × 308 × 889 ) / 77
LCM(913,308,889) = 249990356 / 77
LCM(913,308,889) = 3246628
