Given numbers are 816,280,428,430,325
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 816,280,428,430,325 is 8541296400.
Find LCM of 816,280,428,430,325 with Prime Factorization
| 2 | 816, 280, 428, 430, 325 |
| 2 | 408, 140, 214, 215, 325 |
| 2 | 204, 70, 107, 215, 325 |
| 5 | 102, 35, 107, 215, 325 |
| 102, 7, 107, 43, 65 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 102 x 7 x 107 x 43 x 65 = 8541296400
Therefore, the lowest common multiple of 816,280,428,430,325 is 8541296400.
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.
816 x 280 x 428 x 430 x 325 = 13666074240000
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
428 : 1, 2, 4, 107, 214, 428
430 : 1, 2, 5, 10, 43, 86, 215, 430
325 : 1, 5, 13, 25, 65, 325
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,280,428,430,325, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
280:2x 2x 2x 5x 7
428:2x 2x 107
430:2x 5x 43
325:5x 5x 13
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 2x 2x 5x 5 = 1600
Therefore, the value for common factors is 1600.
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 = 13666074240000/(1x1600)
LCM = 13666074240000/1600
LCM = 8541296400
Thus, we can understand that the LCM of 816,280,428,430,325 is 8541296400.
