Find LCM of 684,819,603,870,490 with Prime Factorization
| 2 | 684, 819, 603, 870, 490 |
| 3 | 342, 819, 603, 435, 245 |
| 3 | 114, 273, 201, 145, 245 |
| 5 | 38, 91, 67, 145, 245 |
| 7 | 38, 91, 67, 29, 49 |
| 38, 13, 67, 29, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 7 x 38 x 13 x 67 x 29 x 7 = 4232903220
Therefore, the lowest common multiple of 684,819,603,870,490 is 4232903220.
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 819 x 603 x 870 x 490 = 144003367544400
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
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
603 : 1, 3, 9, 67, 201, 603
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,819,603,870,490, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
819:3x 3x 7x 13
603:3x 3x 67
870:2x 3x 5x 29
490:2x 5x 7x 7
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 3x 3x 5x 7 = 34020
Therefore, the value for common factors is 34020.
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 = 144003367544400/(1x34020)
LCM = 144003367544400/34020
LCM = 4232903220
Thus, we can understand that the LCM of 684,819,603,870,490 is 4232903220.
