Given numbers are 306,815,369,407,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 306,815,369,407,420 is 58261993020.
Find LCM of 306,815,369,407,420 with Prime Factorization
| 2 | 306, 815, 369, 407, 420 |
| 3 | 153, 815, 369, 407, 210 |
| 3 | 51, 815, 123, 407, 70 |
| 5 | 17, 815, 41, 407, 70 |
| 17, 163, 41, 407, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 17 x 163 x 41 x 407 x 14 = 58261993020
Therefore, the lowest common multiple of 306,815,369,407,420 is 58261993020.
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.
306 x 815 x 369 x 407 x 420 = 15730738115400
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.
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
815 : 1, 5, 163, 815
369 : 1, 3, 9, 41, 123, 369
407 : 1, 11, 37, 407
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 306,815,369,407,420, is 1.
Now, the common factors can be found like this.
306:2x 3x 3x 17
815:5x 163
369:3x 3x 41
407:11x 37
420:2x 2x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 5 = 270
Therefore, the value for common factors is 270.
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 = 15730738115400/(1x270)
LCM = 15730738115400/270
LCM = 58261993020
Thus, we can understand that the LCM of 306,815,369,407,420 is 58261993020.
