So the greatest common factor 672,396,340 is 4.
Lets's calculate LCM of 65,51,33
3 | 65, 51, 33 |
65, 17, 11 |
∴ So the LCM of the given numbers is 3 x 65 x 17 x 11 = 36465
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 4/36465
Therefore, the GCF of Fractions 672/65,396/51,340/33 is 4/36465
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 65,51,33 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(65,51,33) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(65,51,33) x common factors =1 x 3 = 3
LCM(65,51,33) = ( 65 × 51 × 33 ) / 3
LCM(65,51,33) = 109395 / 3
LCM(65,51,33) = 36465
