Given numbers are 689,309,695,333
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 689,309,695,333 is 16424247645.
Find LCM of 689,309,695,333 with Prime Factorization
| 3 | 689, 309, 695, 333 |
| 689, 103, 695, 111 |
Multiply the prime numbers at the bottom and the left side.
3 x 689 x 103 x 695 x 111 = 16424247645
Therefore, the lowest common multiple of 689,309,695,333 is 16424247645.
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.
689 x 309 x 695 x 333 = 49272742935
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.
689 : 1, 13, 53, 689
309 : 1, 3, 103, 309
695 : 1, 5, 139, 695
333 : 1, 3, 9, 37, 111, 333
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,309,695,333, is 1.
Now, the common factors can be found like this.
689:13x 53
309:3x 103
695:5x 139
333:3x 3x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 49272742935/(1x3)
LCM = 49272742935/3
LCM = 16424247645
Thus, we can understand that the LCM of 689,309,695,333 is 16424247645.
