Lets's calculate GCF of 210,140
2 | 210, 140 |
5 | 105, 70 |
7 | 21, 14 |
3, 2 |
∴ So the GCF of the given numbers is 2 x 5 x 7 = 70
Now, list down the factors of 210
:1,2,3,5,6,7,10,14,15,21,30,35,42,70,105,210
Now, list down the factors of 140
:1,2,4,5,7,10,14,20,28,35,70,140
Greatest Common Factor
We found the factors 210,140 . The biggest common factor number is the GCF number.
So the greatest common factor 210,140 is 70.
Lets's calculate LCM of 371,560
7 | 371, 560 |
53, 80 |
∴ So the LCM of the given numbers is 7 x 53 x 80 = 29680
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 70/29680
Therefore, the GCF of Fractions 210/371,140/560 is 70/29680
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 371,560 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(371,560) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(371,560) x common factors =7 x 1 = 7
LCM(371,560) = ( 371 × 560 ) / 7
LCM(371,560) = 207760 / 7
LCM(371,560) = 29680
