Greatest Common Factor
We found the factors 76,448,147 . The biggest common factor number is the GCF number.
So the greatest common factor 76,448,147 is 1.
Lets's calculate LCM of 77,70,331
7 | 77, 70, 331 |
11, 10, 331 |
∴ So the LCM of the given numbers is 7 x 11 x 10 x 331 = 254870
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/254870
Therefore, the GCF of Fractions 76/77,448/70,147/331 is 1/254870
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 77,70,331 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,70,331) = 1
common factors(in case of two or more numbers have common factors) = 7
GCF(77,70,331) x common factors =1 x 7 = 7
LCM(77,70,331) = ( 77 × 70 × 331 ) / 7
LCM(77,70,331) = 1784090 / 7
LCM(77,70,331) = 254870
