Greatest Common Factor
We found the factors 75,86,385 . The biggest common factor number is the GCF number.
So the greatest common factor 75,86,385 is 1.
Lets's calculate LCM of 39,55,666
3 | 39, 55, 666 |
13, 55, 222 |
∴ So the LCM of the given numbers is 3 x 13 x 55 x 222 = 476190
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/476190
Therefore, the GCF of Fractions 75/39,86/55,385/666 is 1/476190
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 39,55,666 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(39,55,666) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(39,55,666) x common factors =1 x 3 = 3
LCM(39,55,666) = ( 39 × 55 × 666 ) / 3
LCM(39,55,666) = 1428570 / 3
LCM(39,55,666) = 476190
