Given numbers are 159,428,689,299
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 159,428,689,299 is 20347548.
Find LCM of 159,428,689,299 with Prime Factorization
| 13 | 159, 428, 689, 299 |
| 53 | 159, 428, 53, 23 |
| 3, 428, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
13 x 53 x 3 x 428 x 1 x 23 = 20347548
Therefore, the lowest common multiple of 159,428,689,299 is 20347548.
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.
159 x 428 x 689 x 299 = 14019460572
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.
159 : 1, 3, 53, 159
428 : 1, 2, 4, 107, 214, 428
689 : 1, 13, 53, 689
299 : 1, 13, 23, 299
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 159,428,689,299, is 1.
Now, the common factors can be found like this.
159:3x 53
428:2x 2x 107
689:13x 53
299:13x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 53 = 689
Therefore, the value for common factors is 689.
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 = 14019460572/(1x689)
LCM = 14019460572/689
LCM = 20347548
Thus, we can understand that the LCM of 159,428,689,299 is 20347548.
