Greatest Common Factor
We found the factors 73,23,64,905 . The biggest common factor number is the GCF number.
So the greatest common factor 73,23,64,905 is 1.
Lets's calculate LCM of 78,57,66,19
2 | 78, 57, 66, 19 |
3 | 39, 57, 33, 19 |
19 | 13, 19, 11, 19 |
13, 1, 11, 1 |
∴ So the LCM of the given numbers is 2 x 3 x 19 x 13 x 1 x 11 x 1 = 16302
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/16302
Therefore, the GCF of Fractions 73/78,23/57,64/66,905/19 is 1/16302
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 78,57,66,19 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(78,57,66,19) = 1
common factors(in case of two or more numbers have common factors) = 342
GCF(78,57,66,19) x common factors =1 x 342 = 342
LCM(78,57,66,19) = ( 78 × 57 × 66 × 19 ) / 342
LCM(78,57,66,19) = 5575284 / 342
LCM(78,57,66,19) = 16302
