1,2,3,4,5,6,10,12,13,15,20,26,30,39,52,60,65,78,130,156,195,260,390,780
Greatest Common Factor
We found the factors 111,721,780 . The biggest common factor number is the GCF number.
So the greatest common factor 111,721,780 is 1.
Lets's calculate LCM of 85,96,20
2 | 85, 96, 20 |
2 | 85, 48, 10 |
5 | 85, 24, 5 |
17, 24, 1 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 17 x 24 x 1 = 8160
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/8160
Therefore, the GCF of Fractions 111/85,721/96,780/20 is 1/8160
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 85,96,20 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(85,96,20) = 1
common factors(in case of two or more numbers have common factors) = 20
GCF(85,96,20) x common factors =1 x 20 = 20
LCM(85,96,20) = ( 85 × 96 × 20 ) / 20
LCM(85,96,20) = 163200 / 20
LCM(85,96,20) = 8160
