Find LCM of 306,220,989,468,286 with Prime Factorization
| 2 | 306, 220, 989, 468, 286 |
| 2 | 153, 110, 989, 234, 143 |
| 3 | 153, 55, 989, 117, 143 |
| 3 | 51, 55, 989, 39, 143 |
| 11 | 17, 55, 989, 13, 143 |
| 13 | 17, 5, 989, 13, 13 |
| 17, 5, 989, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 11 x 13 x 17 x 5 x 989 x 1 x 1 = 432766620
Therefore, the lowest common multiple of 306,220,989,468,286 is 432766620.
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.
306 x 220 x 989 x 468 x 286 = 8911530239040
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.
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
989 : 1, 23, 43, 989
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
286 : 1, 2, 11, 13, 22, 26, 143, 286
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 306,220,989,468,286, is 1.
Now, the common factors can be found like this.
306:2x 3x 3x 17
220:2x 2x 5x 11
989:23x 43
468:2x 2x 3x 3x 13
286:2x 11x 13
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 2x 2x 3x 3x 11x 13 = 20592
Therefore, the value for common factors is 20592.
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 = 8911530239040/(1x20592)
LCM = 8911530239040/20592
LCM = 432766620
Thus, we can understand that the LCM of 306,220,989,468,286 is 432766620.
