Given numbers are 609,870,945,913
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 609,870,945,913 is 50041530.
Find LCM of 609,870,945,913 with Prime Factorization
| 3 | 609, 870, 945, 913 |
| 5 | 203, 290, 315, 913 |
| 7 | 203, 58, 63, 913 |
| 29 | 29, 58, 9, 913 |
| 1, 2, 9, 913 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 29 x 1 x 2 x 9 x 913 = 50041530
Therefore, the lowest common multiple of 609,870,945,913 is 50041530.
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.
609 x 870 x 945 x 913 = 457129376550
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.
609 : 1, 3, 7, 21, 29, 87, 203, 609
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
913 : 1, 11, 83, 913
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 609,870,945,913, is 1.
Now, the common factors can be found like this.
609:3x 7x 29
870:2x 3x 5x 29
945:3x 3x 3x 5x 7
913:11x 83
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 7x 29 = 9135
Therefore, the value for common factors is 9135.
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 = 457129376550/(1x9135)
LCM = 457129376550/9135
LCM = 50041530
Thus, we can understand that the LCM of 609,870,945,913 is 50041530.
