Find LCM of 684,786,817,157,893 with Prime Factorization
| 2 | 684, 786, 817, 157, 893 |
| 3 | 342, 393, 817, 157, 893 |
| 19 | 114, 131, 817, 157, 893 |
| 6, 131, 43, 157, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 6 x 131 x 43 x 157 x 47 = 28431080388
Therefore, the lowest common multiple of 684,786,817,157,893 is 28431080388.
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 786 x 817 x 157 x 893 = 61581720120408
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
786 : 1, 2, 3, 6, 131, 262, 393, 786
817 : 1, 19, 43, 817
157 : 1, 157
893 : 1, 19, 47, 893
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,786,817,157,893, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
786:2x 3x 131
817:19x 43
157:157
893:19x 47
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 19x 19 = 2166
Therefore, the value for common factors is 2166.
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 = 61581720120408/(1x2166)
LCM = 61581720120408/2166
LCM = 28431080388
Thus, we can understand that the LCM of 684,786,817,157,893 is 28431080388.
