Given numbers are 261,748,748,906
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 261,748,748,906 is 29479428.
Find LCM of 261,748,748,906 with Prime Factorization
| 2 | 261, 748, 748, 906 |
| 2 | 261, 374, 374, 453 |
| 3 | 261, 187, 187, 453 |
| 11 | 87, 187, 187, 151 |
| 17 | 87, 17, 17, 151 |
| 87, 1, 1, 151 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 17 x 87 x 1 x 1 x 151 = 29479428
Therefore, the lowest common multiple of 261,748,748,906 is 29479428.
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.
261 x 748 x 748 x 906 = 132303672864
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.
261 : 1, 3, 9, 29, 87, 261
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
906 : 1, 2, 3, 6, 151, 302, 453, 906
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 261,748,748,906, is 1.
Now, the common factors can be found like this.
261:3x 3x 29
748:2x 2x 11x 17
748:2x 2x 11x 17
906:2x 3x 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 2x 3x 11x 17 = 4488
Therefore, the value for common factors is 4488.
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 = 132303672864/(1x4488)
LCM = 132303672864/4488
LCM = 29479428
Thus, we can understand that the LCM of 261,748,748,906 is 29479428.
