Given numbers are 130,231,903,693
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 130,231,903,693 is 3873870.
Find LCM of 130,231,903,693 with Prime Factorization
| 3 | 130, 231, 903, 693 |
| 7 | 130, 77, 301, 231 |
| 11 | 130, 11, 43, 33 |
| 130, 1, 43, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 11 x 130 x 1 x 43 x 3 = 3873870
Therefore, the lowest common multiple of 130,231,903,693 is 3873870.
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.
130 x 231 x 903 x 693 = 18792143370
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.
130 : 1, 2, 5, 10, 13, 26, 65, 130
231 : 1, 3, 7, 11, 21, 33, 77, 231
903 : 1, 3, 7, 21, 43, 129, 301, 903
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 130,231,903,693, is 1.
Now, the common factors can be found like this.
130:2x 5x 13
231:3x 7x 11
903:3x 7x 43
693:3x 3x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7x 7x 11 = 4851
Therefore, the value for common factors is 4851.
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 = 18792143370/(1x4851)
LCM = 18792143370/4851
LCM = 3873870
Thus, we can understand that the LCM of 130,231,903,693 is 3873870.
