Given numbers are 637,845,906,231
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 637,845,906,231 is 412642230.
Find LCM of 637,845,906,231 with Prime Factorization
| 3 | 637, 845, 906, 231 |
| 7 | 637, 845, 302, 77 |
| 13 | 91, 845, 302, 11 |
| 7, 65, 302, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 13 x 7 x 65 x 302 x 11 = 412642230
Therefore, the lowest common multiple of 637,845,906,231 is 412642230.
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.
637 x 845 x 906 x 231 = 112651328790
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.
637 : 1, 7, 13, 49, 91, 637
845 : 1, 5, 13, 65, 169, 845
906 : 1, 2, 3, 6, 151, 302, 453, 906
231 : 1, 3, 7, 11, 21, 33, 77, 231
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,845,906,231, is 1.
Now, the common factors can be found like this.
637:7x 7x 13
845:5x 13x 13
906:2x 3x 151
231:3x 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 7x 13 = 273
Therefore, the value for common factors is 273.
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 = 112651328790/(1x273)
LCM = 112651328790/273
LCM = 412642230
Thus, we can understand that the LCM of 637,845,906,231 is 412642230.
