Given numbers are 380,608,309,755
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 380,608,309,755 is 141843360.
Find LCM of 380,608,309,755 with Prime Factorization
| 2 | 380, 608, 309, 755 |
| 2 | 190, 304, 309, 755 |
| 5 | 95, 152, 309, 755 |
| 19 | 19, 152, 309, 151 |
| 1, 8, 309, 151 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 19 x 1 x 8 x 309 x 151 = 141843360
Therefore, the lowest common multiple of 380,608,309,755 is 141843360.
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.
380 x 608 x 309 x 755 = 53900476800
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.
380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
309 : 1, 3, 103, 309
755 : 1, 5, 151, 755
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 380,608,309,755, is 1.
Now, the common factors can be found like this.
380:2x 2x 5x 19
608:2x 2x 2x 2x 2x 19
309:3x 103
755:5x 151
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 5x 19 = 380
Therefore, the value for common factors is 380.
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 = 53900476800/(1x380)
LCM = 53900476800/380
LCM = 141843360
Thus, we can understand that the LCM of 380,608,309,755 is 141843360.
