1,13
Greatest Common Factor
We found the factors 15,40,96,13 . The biggest common factor number is the GCF number.
So the greatest common factor 15,40,96,13 is 1.
Lets's calculate LCM of 19,73,78,326
2 | 19, 73, 78, 326 |
19, 73, 39, 163 |
∴ So the LCM of the given numbers is 2 x 19 x 73 x 39 x 163 = 17634318
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/17634318
Therefore, the GCF of Fractions 15/19,40/73,96/78,13/326 is 1/17634318
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 19,73,78,326 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(19,73,78,326) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(19,73,78,326) x common factors =1 x 2 = 2
LCM(19,73,78,326) = ( 19 × 73 × 78 × 326 ) / 2
LCM(19,73,78,326) = 35268636 / 2
LCM(19,73,78,326) = 17634318
