Given numbers are 523,828,990,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 523,828,990,870 is 690705180.
Find LCM of 523,828,990,870 with Prime Factorization
| 2 | 523, 828, 990, 870 |
| 3 | 523, 414, 495, 435 |
| 3 | 523, 138, 165, 145 |
| 5 | 523, 46, 55, 145 |
| 523, 46, 11, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 523 x 46 x 11 x 29 = 690705180
Therefore, the lowest common multiple of 523,828,990,870 is 690705180.
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.
523 x 828 x 990 x 870 = 372980797200
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.
523 : 1, 523
828 : 1, 2, 3, 4, 6, 9, 12, 18, 23, 36, 46, 69, 92, 138, 207, 276, 414, 828
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 523,828,990,870, is 1.
Now, the common factors can be found like this.
523:523
828:2x 2x 3x 3x 23
990:2x 3x 3x 5x 11
870:2x 3x 5x 29
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 3x 3x 3x 5 = 540
Therefore, the value for common factors is 540.
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 = 372980797200/(1x540)
LCM = 372980797200/540
LCM = 690705180
Thus, we can understand that the LCM of 523,828,990,870 is 690705180.
