Given numbers are 732,689,169,738,406
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 732,689,169,738,406 is 163709847756.
Find LCM of 732,689,169,738,406 with Prime Factorization
| 2 | 732, 689, 169, 738, 406 |
| 3 | 366, 689, 169, 369, 203 |
| 13 | 122, 689, 169, 123, 203 |
| 122, 53, 13, 123, 203 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 122 x 53 x 13 x 123 x 203 = 163709847756
Therefore, the lowest common multiple of 732,689,169,738,406 is 163709847756.
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.
732 x 689 x 169 x 738 x 406 = 25538736249936
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.
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
689 : 1, 13, 53, 689
169 : 1, 13, 169
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
406 : 1, 2, 7, 14, 29, 58, 203, 406
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 732,689,169,738,406, is 1.
Now, the common factors can be found like this.
732:2x 2x 3x 61
689:13x 53
169:13x 13
738:2x 3x 3x 41
406:2x 7x 29
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 13 = 156
Therefore, the value for common factors is 156.
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 = 25538736249936/(1x156)
LCM = 25538736249936/156
LCM = 163709847756
Thus, we can understand that the LCM of 732,689,169,738,406 is 163709847756.
