:1,2,4,7,14,28
Now, list down the factors of 889
:1,7,127,889
Now, list down the factors of 756
:1,2,3,4,6,7,9,12,14,18,21,27,28,36,42,54,63,84,108,126,189,252,378,756
Greatest Common Factor
We found the factors 28,889,756 . The biggest common factor number is the GCF number.
So the greatest common factor 28,889,756 is 7.
Lets's calculate LCM of 77,50,208
2 | 77, 50, 208 |
77, 25, 104 |
∴ So the LCM of the given numbers is 2 x 77 x 25 x 104 = 400400
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/400400
Therefore, the GCF of Fractions 28/77,889/50,756/208 is 7/400400
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 77,50,208 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(77,50,208) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(77,50,208) x common factors =1 x 2 = 2
LCM(77,50,208) = ( 77 × 50 × 208 ) / 2
LCM(77,50,208) = 800800 / 2
LCM(77,50,208) = 400400
