Find LCM of 731,684,351,408,215 with Prime Factorization
2 | 731, 684, 351, 408, 215 |
2 | 731, 342, 351, 204, 215 |
3 | 731, 171, 351, 102, 215 |
3 | 731, 57, 117, 34, 215 |
17 | 731, 19, 39, 34, 215 |
43 | 43, 19, 39, 2, 215 |
1, 19, 39, 2, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 17 x 43 x 1 x 19 x 39 x 2 x 5 = 195001560
Therefore, the lowest common multiple of 731,684,351,408,215 is 195001560.
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.
731 x 684 x 351 x 408 x 215 = 15394983158880
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.
731 : 1, 17, 43, 731
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
351 : 1, 3, 9, 13, 27, 39, 117, 351
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
215 : 1, 5, 43, 215
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,684,351,408,215, is 1.
Now, the common factors can be found like this.
731:17x 43
684:2x 2x 3x 3x 19
351:3x 3x 3x 13
408:2x 2x 2x 3x 17
215:5x 43
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 17x 43 = 78948
Therefore, the value for common factors is 78948.
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 = 15394983158880/(1x78948)
LCM = 15394983158880/78948
LCM = 195001560
Thus, we can understand that the LCM of 731,684,351,408,215 is 195001560.
