Lets's calculate GCF of 651,868
7 | 651, 868 |
31 | 93, 124 |
3, 4 |
∴ So the GCF of the given numbers is 7 x 31 = 217
Now, list down the factors of 651
:1,3,7,21,31,93,217,651
Now, list down the factors of 868
:1,2,4,7,14,28,31,62,124,217,434,868
Greatest Common Factor
We found the factors 651,868 . The biggest common factor number is the GCF number.
So the greatest common factor 651,868 is 217.
Lets's calculate LCM of 65,815
5 | 65, 815 |
13, 163 |
∴ So the LCM of the given numbers is 5 x 13 x 163 = 10595
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 217/10595
Therefore, the GCF of Fractions 651/65,868/815 is 217/10595
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 65,815 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(65,815) = 5
common factors(in case of two or more numbers have common factors) = 1
GCF(65,815) x common factors =5 x 1 = 5
LCM(65,815) = ( 65 × 815 ) / 5
LCM(65,815) = 52975 / 5
LCM(65,815) = 10595
