Find LCM of 918,694,391,846 with Prime Factorization
| 2 | 918, 694, 391, 846 |
| 3 | 459, 347, 391, 423 |
| 3 | 153, 347, 391, 141 |
| 17 | 51, 347, 391, 47 |
| 3, 347, 23, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 17 x 3 x 347 x 23 x 47 = 344348226
Therefore, the lowest common multiple of 918,694,391,846 is 344348226.
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.
918 x 694 x 391 x 846 = 210741114312
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.
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
694 : 1, 2, 347, 694
391 : 1, 17, 23, 391
846 : 1, 2, 3, 6, 9, 18, 47, 94, 141, 282, 423, 846
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 918,694,391,846, is 1.
Now, the common factors can be found like this.
918:2x 3x 3x 3x 17
694:2x 347
391:17x 23
846:2x 3x 3x 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 2x 3x 3x 17 = 612
Therefore, the value for common factors is 612.
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 = 210741114312/(1x612)
LCM = 210741114312/612
LCM = 344348226
Thus, we can understand that the LCM of 918,694,391,846 is 344348226.
