Greatest Common Factor
We found the factors 699,201,813 . The biggest common factor number is the GCF number.
So the greatest common factor 699,201,813 is 3.
Lets's calculate LCM of 15,78,791
3 | 15, 78, 791 |
5, 26, 791 |
∴ So the LCM of the given numbers is 3 x 5 x 26 x 791 = 308490
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 3/308490
Therefore, the GCF of Fractions 699/15,201/78,813/791 is 3/308490
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 15,78,791 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(15,78,791) = 1
common factors(in case of two or more numbers have common factors) = 3
GCF(15,78,791) x common factors =1 x 3 = 3
LCM(15,78,791) = ( 15 × 78 × 791 ) / 3
LCM(15,78,791) = 925470 / 3
LCM(15,78,791) = 308490
