Given numbers are 287,910,448,884
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 287,910,448,884 is 20296640.
Find LCM of 287,910,448,884 with Prime Factorization
| 2 | 287, 910, 448, 884 |
| 2 | 287, 455, 224, 442 |
| 7 | 287, 455, 112, 221 |
| 13 | 41, 65, 16, 221 |
| 41, 5, 16, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 13 x 41 x 5 x 16 x 17 = 20296640
Therefore, the lowest common multiple of 287,910,448,884 is 20296640.
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.
287 x 910 x 448 x 884 = 103431677440
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.
287 : 1, 7, 41, 287
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,910,448,884, is 1.
Now, the common factors can be found like this.
287:7x 41
910:2x 5x 7x 13
448:2x 2x 2x 2x 2x 2x 7
884:2x 2x 13x 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 7x 7x 13 = 5096
Therefore, the value for common factors is 5096.
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 = 103431677440/(1x5096)
LCM = 103431677440/5096
LCM = 20296640
Thus, we can understand that the LCM of 287,910,448,884 is 20296640.
