Find LCM of 909,981,817,665,799 with Prime Factorization
| 3 | 909, 981, 817, 665, 799 |
| 3 | 303, 327, 817, 665, 799 |
| 19 | 101, 109, 817, 665, 799 |
| 101, 109, 43, 35, 799 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 19 x 101 x 109 x 43 x 35 x 799 = 2263743734805
Therefore, the lowest common multiple of 909,981,817,665,799 is 2263743734805.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
909 x 981 x 817 x 665 x 799 = 387100178651655
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
909 : 1, 3, 9, 101, 303, 909
981 : 1, 3, 9, 109, 327, 981
817 : 1, 19, 43, 817
665 : 1, 5, 7, 19, 35, 95, 133, 665
799 : 1, 17, 47, 799
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 909,981,817,665,799, is 1.
Now, the common factors can be found like this.
909:3x 3x 101
981:3x 3x 109
817:19x 43
665:5x 7x 19
799:17x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 19 = 171
Therefore, the value for common factors is 171.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 387100178651655/(1x171)
LCM = 387100178651655/171
LCM = 2263743734805
Thus, we can understand that the LCM of 909,981,817,665,799 is 2263743734805.
