Lets's calculate GCF of 680,122
2 | 680, 122 |
340, 61 |
∴ So the GCF of the given numbers is 2 = 2
Now, list down the factors of 680
:1,2,4,5,8,10,17,20,34,40,68,85,136,170,340,680
Now, list down the factors of 122
:1,2,61,122
Greatest Common Factor
We found the factors 680,122 . The biggest common factor number is the GCF number.
So the greatest common factor 680,122 is 2.
Lets's calculate LCM of 940,287
Given numbers has no common factors except 1. So, there LCM is their product i.e 269780
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 2/269780
Therefore, the GCF of Fractions 680/940,122/287 is 2/269780
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 940,287 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(940,287) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(940,287) x common factors =1 x 1 = 1
LCM(940,287) = ( 940 × 287 ) / 1
LCM(940,287) = 269780 / 1
LCM(940,287) = 269780
