Lets's calculate GCF of 870,397
∴ So GCF of numbers is 1 because of no common factors present between them.
Now, list down the factors of 870
:1,2,3,5,6,10,15,29,30,58,87,145,174,290,435,870
Now, list down the factors of 397
:1,397
Greatest Common Factor
We found the factors 870,397 . The biggest common factor number is the GCF number.
So the greatest common factor 870,397 is 1.
Lets's calculate LCM of 931,945
7 | 931, 945 |
133, 135 |
∴ So the LCM of the given numbers is 7 x 133 x 135 = 125685
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/125685
Therefore, the GCF of Fractions 870/931,397/945 is 1/125685
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 931,945 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(931,945) = 7
common factors(in case of two or more numbers have common factors) = 1
GCF(931,945) x common factors =7 x 1 = 7
LCM(931,945) = ( 931 × 945 ) / 7
LCM(931,945) = 879795 / 7
LCM(931,945) = 125685
