The HCF of 729,162 is 81.
Lets's calculate GCF of 729,162
3 | 729, 162 |
3 | 243, 54 |
3 | 81, 18 |
3 | 27, 6 |
9, 2 |
∴ So the GCF of the given numbers is 3 x 3 x 3 x 3 = 81
Now, list down the factors of 729
:1,3,9,27,81,243,729
Now, list down the factors of 162
:1,2,3,6,9,18,27,54,81,162
Greatest Common Factor
We found the factors 729,162 . The biggest common factor number is the GCF number.
So the greatest common factor 729,162 is 81.
Lets's calculate LCM of 88,580
2 | 88, 580 |
2 | 44, 290 |
22, 145 |
∴ So the LCM of the given numbers is 2 x 2 x 22 x 145 = 12760
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 81/12760
Therefore, the GCF of Fractions 729/88,162/580 is 81/12760
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 88,580 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(88,580) = 4
common factors(in case of two or more numbers have common factors) = 1
GCF(88,580) x common factors =4 x 1 = 4
LCM(88,580) = ( 88 × 580 ) / 4
LCM(88,580) = 51040 / 4
LCM(88,580) = 12760
