Given numbers are 500,870,268,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 500,870,268,990 is 96178500.
Find LCM of 500,870,268,990 with Prime Factorization
| 2 | 500, 870, 268, 990 |
| 2 | 250, 435, 134, 495 |
| 3 | 125, 435, 67, 495 |
| 5 | 125, 145, 67, 165 |
| 25, 29, 67, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 25 x 29 x 67 x 33 = 96178500
Therefore, the lowest common multiple of 500,870,268,990 is 96178500.
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.
500 x 870 x 268 x 990 = 115414200000
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.
500 : 1, 2, 4, 5, 10, 20, 25, 50, 100, 125, 250, 500
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
268 : 1, 2, 4, 67, 134, 268
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
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 500,870,268,990, is 2.
Now, the common factors can be found like this.
500:2x 2x 5x 5x 5
870:2x 3x 5x 29
268:2x 2x 67
990:2x 3x 3x 5x 11
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 3x 5x 5 = 600
Therefore, the value for common factors is 600.
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 = 115414200000/(2x600)
LCM = 115414200000/1200
LCM = 96178500
Thus, we can understand that the LCM of 500,870,268,990 is 96178500.
