So the greatest common factor 37,428,620 is 1.
Lets's calculate LCM of 85,17,153
17 | 85, 17, 153 |
5, 1, 9 |
∴ So the LCM of the given numbers is 17 x 5 x 1 x 9 = 765
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/765
Therefore, the GCF of Fractions 37/85,428/17,620/153 is 1/765
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 85,17,153 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,17,153) = 17
common factors(in case of two or more numbers have common factors) = 17
GCF(85,17,153) x common factors =17 x 17 = 289
LCM(85,17,153) = ( 85 × 17 × 153 ) / 289
LCM(85,17,153) = 221085 / 289
LCM(85,17,153) = 765
