Given numbers are 309,490,275,900,897
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 309,490,275,900,897 is 14939624700.
Find LCM of 309,490,275,900,897 with Prime Factorization
| 2 | 309, 490, 275, 900, 897 |
| 3 | 309, 245, 275, 450, 897 |
| 5 | 103, 245, 275, 150, 299 |
| 5 | 103, 49, 55, 30, 299 |
| 103, 49, 11, 6, 299 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 5 x 103 x 49 x 11 x 6 x 299 = 14939624700
Therefore, the lowest common multiple of 309,490,275,900,897 is 14939624700.
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.
309 x 490 x 275 x 900 x 897 = 33614155575000
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.
309 : 1, 3, 103, 309
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
275 : 1, 5, 11, 25, 55, 275
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
897 : 1, 3, 13, 23, 39, 69, 299, 897
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,490,275,900,897, is 1.
Now, the common factors can be found like this.
309:3x 103
490:2x 5x 7x 7
275:5x 5x 11
900:2x 2x 3x 3x 5x 5
897:3x 13x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 5x 5 = 2250
Therefore, the value for common factors is 2250.
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 = 33614155575000/(1x2250)
LCM = 33614155575000/2250
LCM = 14939624700
Thus, we can understand that the LCM of 309,490,275,900,897 is 14939624700.
