The LCM of 891,660,293,396 is 5221260.
Find LCM of 891,660,293,396 with Prime Factorization
| 2 | 891, 660, 293, 396 |
| 2 | 891, 330, 293, 198 |
| 3 | 891, 165, 293, 99 |
| 3 | 297, 55, 293, 33 |
| 11 | 99, 55, 293, 11 |
| 9, 5, 293, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 11 x 9 x 5 x 293 x 1 = 5221260
Therefore, the lowest common multiple of 891,660,293,396 is 5221260.
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.
891 x 660 x 293 x 396 = 68231425680
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.
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
293 : 1, 293
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 891,660,293,396, is 1.
Now, the common factors can be found like this.
891:3x 3x 3x 3x 11
660:2x 2x 3x 5x 11
293:293
396:2x 2x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 3x 11x 11 = 13068
Therefore, the value for common factors is 13068.
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 = 68231425680/(1x13068)
LCM = 68231425680/13068
LCM = 5221260
Thus, we can understand that the LCM of 891,660,293,396 is 5221260.
