Given numbers are 414,646,646,959
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 414,646,646,959 is 128239398.
Find LCM of 414,646,646,959 with Prime Factorization
| 2 | 414, 646, 646, 959 |
| 17 | 207, 323, 323, 959 |
| 19 | 207, 19, 19, 959 |
| 207, 1, 1, 959 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 19 x 207 x 1 x 1 x 959 = 128239398
Therefore, the lowest common multiple of 414,646,646,959 is 128239398.
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.
414 x 646 x 646 x 959 = 165685302216
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.
414 : 1, 2, 3, 6, 9, 18, 23, 46, 69, 138, 207, 414
646 : 1, 2, 17, 19, 34, 38, 323, 646
646 : 1, 2, 17, 19, 34, 38, 323, 646
959 : 1, 7, 137, 959
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 414,646,646,959, is 1.
Now, the common factors can be found like this.
414:2x 3x 3x 23
646:2x 17x 19
646:2x 17x 19
959:7x 137
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 17x 19 = 1292
Therefore, the value for common factors is 1292.
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 = 165685302216/(1x1292)
LCM = 165685302216/1292
LCM = 128239398
Thus, we can understand that the LCM of 414,646,646,959 is 128239398.
