Find LCM of 684,115,161,554,786 with Prime Factorization
| 2 | 684, 115, 161, 554, 786 |
| 3 | 342, 115, 161, 277, 393 |
| 23 | 114, 115, 161, 277, 131 |
| 114, 5, 7, 277, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 23 x 114 x 5 x 7 x 277 x 131 = 19980347940
Therefore, the lowest common multiple of 684,115,161,554,786 is 19980347940.
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 115 x 161 x 554 x 786 = 5514576031440
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
115 : 1, 5, 23, 115
161 : 1, 7, 23, 161
554 : 1, 2, 277, 554
786 : 1, 2, 3, 6, 131, 262, 393, 786
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,115,161,554,786, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
115:5x 23
161:7x 23
554:2x 277
786:2x 3x 131
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 23 = 276
Therefore, the value for common factors is 276.
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 = 5514576031440/(1x276)
LCM = 5514576031440/276
LCM = 19980347940
Thus, we can understand that the LCM of 684,115,161,554,786 is 19980347940.
