The LCM of 684,648,817,286 is 75706488.
Find LCM of 684,648,817,286 with Prime Factorization
| 2 | 684, 648, 817, 286 |
| 2 | 342, 324, 817, 143 |
| 3 | 171, 162, 817, 143 |
| 3 | 57, 54, 817, 143 |
| 19 | 19, 18, 817, 143 |
| 1, 18, 43, 143 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 19 x 1 x 18 x 43 x 143 = 75706488
Therefore, the lowest common multiple of 684,648,817,286 is 75706488.
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.
684 x 648 x 817 x 286 = 103566475584
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
817 : 1, 19, 43, 817
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 684,648,817,286, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
648:2x 2x 2x 3x 3x 3x 3
817:19x 43
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 3x 3x 19 = 1368
Therefore, the value for common factors is 1368.
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 = 103566475584/(1x1368)
LCM = 103566475584/1368
LCM = 75706488
Thus, we can understand that the LCM of 684,648,817,286 is 75706488.
