5 | 765, 460 |
153, 92 |
∴ So the GCF of the given numbers is 5 = 5
Now, list down the factors of 765
:1,3,5,9,15,17,45,51,85,153,255,765
Now, list down the factors of 460
:1,2,4,5,10,20,23,46,92,115,230,460
Greatest Common Factor
We found the factors 765,460 . The biggest common factor number is the GCF number.
So the greatest common factor 765,460 is 5.
Lets's calculate LCM of 51,1921
17 | 51, 1921 |
3, 113 |
∴ So the LCM of the given numbers is 17 x 3 x 113 = 5763
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 5/5763
Therefore, the GCF of Fractions 765/51,460/1921 is 5/5763
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 51,1921 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(51,1921) = 17
common factors(in case of two or more numbers have common factors) = 1
GCF(51,1921) x common factors =17 x 1 = 17
LCM(51,1921) = ( 51 × 1921 ) / 17
LCM(51,1921) = 97971 / 17
LCM(51,1921) = 5763
