1,2,4,8,16,19,38,76,152,304
Greatest Common Factor
We found the factors 84,65,73,304 . The biggest common factor number is the GCF number.
So the greatest common factor 84,65,73,304 is 1.
Lets's calculate LCM of 45,26,54,71
2 | 45, 26, 54, 71 |
3 | 45, 13, 27, 71 |
3 | 15, 13, 9, 71 |
5, 13, 3, 71 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 5 x 13 x 3 x 71 = 249210
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/249210
Therefore, the GCF of Fractions 84/45,65/26,73/54,304/71 is 1/249210
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 45,26,54,71 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(45,26,54,71) = 1
common factors(in case of two or more numbers have common factors) = 18
GCF(45,26,54,71) x common factors =1 x 18 = 18
LCM(45,26,54,71) = ( 45 × 26 × 54 × 71 ) / 18
LCM(45,26,54,71) = 4485780 / 18
LCM(45,26,54,71) = 249210
