Given numbers are 180,240,855,248
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 180,240,855,248 is 424080.
Find LCM of 180,240,855,248 with Prime Factorization
| 2 | 180, 240, 855, 248 |
| 2 | 90, 120, 855, 124 |
| 2 | 45, 60, 855, 62 |
| 3 | 45, 30, 855, 31 |
| 3 | 15, 10, 285, 31 |
| 5 | 5, 10, 95, 31 |
| 1, 2, 19, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 1 x 2 x 19 x 31 = 424080
Therefore, the lowest common multiple of 180,240,855,248 is 424080.
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.
180 x 240 x 855 x 248 = 9160128000
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.
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
248 : 1, 2, 4, 8, 31, 62, 124, 248
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 180,240,855,248, is 1.
Now, the common factors can be found like this.
180:2x 2x 3x 3x 5
240:2x 2x 2x 2x 3x 5
855:3x 3x 5x 19
248:2x 2x 2x 31
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 3x 3x 3x 5x 5 = 21600
Therefore, the value for common factors is 21600.
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 = 9160128000/(1x21600)
LCM = 9160128000/21600
LCM = 424080
Thus, we can understand that the LCM of 180,240,855,248 is 424080.
