Given numbers are 5,638,638,806
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 5,638,638,806 is 1285570.
Find LCM of 5,638,638,806 with Prime Factorization
| 2 | 5, 638, 638, 806 |
| 11 | 5, 319, 319, 403 |
| 29 | 5, 29, 29, 403 |
| 5, 1, 1, 403 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 29 x 5 x 1 x 1 x 403 = 1285570
Therefore, the lowest common multiple of 5,638,638,806 is 1285570.
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.
5 x 638 x 638 x 806 = 1640387320
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.
5 : 1, 5
638 : 1, 2, 11, 22, 29, 58, 319, 638
638 : 1, 2, 11, 22, 29, 58, 319, 638
806 : 1, 2, 13, 26, 31, 62, 403, 806
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 5,638,638,806, is 1.
Now, the common factors can be found like this.
5:5
638:2x 11x 29
638:2x 11x 29
806:2x 13x 31
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 11x 29 = 1276
Therefore, the value for common factors is 1276.
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 = 1640387320/(1x1276)
LCM = 1640387320/1276
LCM = 1285570
Thus, we can understand that the LCM of 5,638,638,806 is 1285570.
