The LCM of 229,780,215,891,154 is 15968092140.
Find LCM of 229,780,215,891,154 with Prime Factorization
| 2 | 229, 780, 215, 891, 154 |
| 3 | 229, 390, 215, 891, 77 |
| 5 | 229, 130, 215, 297, 77 |
| 11 | 229, 26, 43, 297, 77 |
| 229, 26, 43, 27, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 229 x 26 x 43 x 27 x 7 = 15968092140
Therefore, the lowest common multiple of 229,780,215,891,154 is 15968092140.
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.
229 x 780 x 215 x 891 x 154 = 5269470406200
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.
229 : 1, 229
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
215 : 1, 5, 43, 215
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
154 : 1, 2, 7, 11, 14, 22, 77, 154
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 229,780,215,891,154, is 1.
Now, the common factors can be found like this.
229:229
780:2x 2x 3x 5x 13
215:5x 43
891:3x 3x 3x 3x 11
154:2x 7x 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 3x 5x 11 = 330
Therefore, the value for common factors is 330.
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 = 5269470406200/(1x330)
LCM = 5269470406200/330
LCM = 15968092140
Thus, we can understand that the LCM of 229,780,215,891,154 is 15968092140.
