1,5,7,25,35,125,175,875
Greatest Common Factor
We found the factors 217,139,875 . The biggest common factor number is the GCF number.
So the greatest common factor 217,139,875 is 1.
Lets's calculate LCM of 91,12,57
3 | 91, 12, 57 |
91, 4, 19 |
∴ So the LCM of the given numbers is 3 x 91 x 4 x 19 = 20748
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/20748
Therefore, the GCF of Fractions 217/91,139/12,875/57 is 1/20748
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 91,12,57 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(91,12,57) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(91,12,57) x common factors =1 x 3 = 3
LCM(91,12,57) = ( 91 × 12 × 57 ) / 3
LCM(91,12,57) = 62244 / 3
LCM(91,12,57) = 20748
