1,73
Greatest Common Factor
We found the factors 79,40,10,73 . The biggest common factor number is the GCF number.
So the greatest common factor 79,40,10,73 is 1.
Lets's calculate LCM of 17,68,54,225
2 | 17, 68, 54, 225 |
3 | 17, 34, 27, 225 |
3 | 17, 34, 9, 75 |
17 | 17, 34, 3, 25 |
1, 2, 3, 25 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 17 x 1 x 2 x 3 x 25 = 45900
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/45900
Therefore, the GCF of Fractions 79/17,40/68,10/54,73/225 is 1/45900
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 17,68,54,225 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,68,54,225) = 1
common factors(in case of two or more numbers have common factors) = 306
GCF(17,68,54,225) x common factors =1 x 306 = 306
LCM(17,68,54,225) = ( 17 × 68 × 54 × 225 ) / 306
LCM(17,68,54,225) = 14045400 / 306
LCM(17,68,54,225) = 45900
