Greatest Common Factor
We found the factors 78,49,901 . The biggest common factor number is the GCF number.
So the greatest common factor 78,49,901 is 1.
Lets's calculate LCM of 97,65,45
5 | 97, 65, 45 |
97, 13, 9 |
∴ So the LCM of the given numbers is 5 x 97 x 13 x 9 = 56745
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/56745
Therefore, the GCF of Fractions 78/97,49/65,901/45 is 1/56745
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 97,65,45 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(97,65,45) = 1
common factors(in case of two or more numbers have common factors) = 5
GCF(97,65,45) x common factors =1 x 5 = 5
LCM(97,65,45) = ( 97 × 65 × 45 ) / 5
LCM(97,65,45) = 283725 / 5
LCM(97,65,45) = 56745
