So the greatest common factor 715,858 is 143.
Lets's calculate LCM of 759,108
3 | 759, 108 |
253, 36 |
∴ So the LCM of the given numbers is 3 x 253 x 36 = 27324
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 143/27324
Therefore, the GCF of Fractions 715/759,858/108 is 143/27324
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 759,108 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(759,108) = 3
common factors(in case of two or more numbers have common factors) = 1
GCF(759,108) x common factors =3 x 1 = 3
LCM(759,108) = ( 759 × 108 ) / 3
LCM(759,108) = 81972 / 3
LCM(759,108) = 27324
