Given numbers are 320,309,876,249,257
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 320,309,876,249,257 is 153972277440.
Find LCM of 320,309,876,249,257 with Prime Factorization
| 2 | 320, 309, 876, 249, 257 |
| 2 | 160, 309, 438, 249, 257 |
| 3 | 80, 309, 219, 249, 257 |
| 80, 103, 73, 83, 257 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 80 x 103 x 73 x 83 x 257 = 153972277440
Therefore, the lowest common multiple of 320,309,876,249,257 is 153972277440.
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.
320 x 309 x 876 x 249 x 257 = 5543001987840
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.
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
309 : 1, 3, 103, 309
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
249 : 1, 3, 83, 249
257 : 1, 257
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 320,309,876,249,257, is 1.
Now, the common factors can be found like this.
320:2x 2x 2x 2x 2x 2x 5
309:3x 103
876:2x 2x 3x 73
249:3x 83
257:257
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 3 = 36
Therefore, the value for common factors is 36.
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 = 5543001987840/(1x36)
LCM = 5543001987840/36
LCM = 153972277440
Thus, we can understand that the LCM of 320,309,876,249,257 is 153972277440.
