So the greatest common factor 20,934,342 is 2.
Lets's calculate LCM of 765,608,680
2 | 765, 608, 680 |
2 | 765, 304, 340 |
2 | 765, 152, 170 |
5 | 765, 76, 85 |
17 | 153, 76, 17 |
9, 76, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 2 x 5 x 17 x 9 x 76 x 1 = 465120
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/465120
Therefore, the GCF of Fractions 20/765,934/608,342/680 is 2/465120
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 765,608,680 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(765,608,680) = 1
common factors(in case of two or more numbers have common factors) = 680
GCF(765,608,680) x common factors =1 x 680 = 680
LCM(765,608,680) = ( 765 × 608 × 680 ) / 680
LCM(765,608,680) = 316281600 / 680
LCM(765,608,680) = 465120
