∴ So the GCF of the given numbers is 5 = 5
Now, list down the factors of 595
:1,5,7,17,35,85,119,595
Now, list down the factors of 830
:1,2,5,10,83,166,415,830
Greatest Common Factor
We found the factors 595,830 . The biggest common factor number is the GCF number.
So the greatest common factor 595,830 is 5.
Lets's calculate LCM of 420,280
2 | 420, 280 |
2 | 210, 140 |
5 | 105, 70 |
7 | 21, 14 |
3, 2 |
∴ So the LCM of the given numbers is 2 x 2 x 5 x 7 x 3 x 2 = 840
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/840
Therefore, the GCF of Fractions 595/420,830/280 is 5/840
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 420,280 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(420,280) = 140
common factors(in case of two or more numbers have common factors) = 1
GCF(420,280) x common factors =140 x 1 = 140
LCM(420,280) = ( 420 × 280 ) / 140
LCM(420,280) = 117600 / 140
LCM(420,280) = 840
