7 | 784, 861 |
112, 123 |
∴ So the GCF of the given numbers is 7 = 7
Now, list down the factors of 784
:1,2,4,7,8,14,16,28,49,56,98,112,196,392,784
Now, list down the factors of 861
:1,3,7,21,41,123,287,861
Greatest Common Factor
We found the factors 784,861 . The biggest common factor number is the GCF number.
So the greatest common factor 784,861 is 7.
Lets's calculate LCM of 164,250
2 | 164, 250 |
82, 125 |
∴ So the LCM of the given numbers is 2 x 82 x 125 = 20500
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 7/20500
Therefore, the GCF of Fractions 784/164,861/250 is 7/20500
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 164,250 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(164,250) = 2
common factors(in case of two or more numbers have common factors) = 1
GCF(164,250) x common factors =2 x 1 = 2
LCM(164,250) = ( 164 × 250 ) / 2
LCM(164,250) = 41000 / 2
LCM(164,250) = 20500
