Given numbers are 444,138,420,309,918
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 444,138,420,309,918 is 5632581780.
Find LCM of 444,138,420,309,918 with Prime Factorization
| 2 | 444, 138, 420, 309, 918 |
| 2 | 222, 69, 210, 309, 459 |
| 3 | 111, 69, 105, 309, 459 |
| 37, 23, 35, 103, 153 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 37 x 23 x 35 x 103 x 153 = 5632581780
Therefore, the lowest common multiple of 444,138,420,309,918 is 5632581780.
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.
444 x 138 x 420 x 309 x 918 = 7299825986880
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.
444 : 1, 2, 3, 4, 6, 12, 37, 74, 111, 148, 222, 444
138 : 1, 2, 3, 6, 23, 46, 69, 138
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
309 : 1, 3, 103, 309
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 444,138,420,309,918, is 3.
Now, the common factors can be found like this.
444:2x 2x 3x 37
138:2x 3x 23
420:2x 2x 3x 5x 7
309:3x 103
918:2x 3x 3x 3x 17
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 2x 2x 3x 3x 3 = 432
Therefore, the value for common factors is 432.
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 = 7299825986880/(3x432)
LCM = 7299825986880/1296
LCM = 5632581780
Thus, we can understand that the LCM of 444,138,420,309,918 is 5632581780.
