Factors of 979
List of positive integer factors of 979 that divides 979 without a remainder.
1,11,89,979
Greatest Common Factor
We found the factors 880,423,979 . The biggest common factor number is the GCF number.
So the greatest common factor 880,423,979 is 1.
Lets's calculate LCM of 18,46,72
2 | 18, 46, 72 |
3 | 9, 23, 36 |
3 | 3, 23, 12 |
1, 23, 4 |
∴ So the LCM of the given numbers is 2 x 3 x 3 x 1 x 23 x 4 = 1656
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/1656
Therefore, the GCF of Fractions 880/18,423/46,979/72 is 1/1656
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 18,46,72 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(18,46,72) = 2
common factors(in case of two or more numbers have common factors) = 18
GCF(18,46,72) x common factors =2 x 18 = 36
LCM(18,46,72) = ( 18 × 46 × 72 ) / 36
LCM(18,46,72) = 59616 / 36
LCM(18,46,72) = 1656
