Greatest Common Factor
We found the factors 66,88,145 . The biggest common factor number is the GCF number.
So the greatest common factor 66,88,145 is 1.
Lets's calculate LCM of 69,42,64
2 | 69, 42, 64 |
3 | 69, 21, 32 |
23, 7, 32 |
∴ So the LCM of the given numbers is 2 x 3 x 23 x 7 x 32 = 30912
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/30912
Therefore, the GCF of Fractions 66/69,88/42,145/64 is 1/30912
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 69,42,64 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(69,42,64) = 1
common factors(in case of two or more numbers have common factors) = 6
GCF(69,42,64) x common factors =1 x 6 = 6
LCM(69,42,64) = ( 69 × 42 × 64 ) / 6
LCM(69,42,64) = 185472 / 6
LCM(69,42,64) = 30912
