Given numbers are 715,867,286,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 715,867,286,638 is 35954490.
Find LCM of 715,867,286,638 with Prime Factorization
| 2 | 715, 867, 286, 638 |
| 11 | 715, 867, 143, 319 |
| 13 | 65, 867, 13, 29 |
| 5, 867, 1, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 5 x 867 x 1 x 29 = 35954490
Therefore, the lowest common multiple of 715,867,286,638 is 35954490.
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.
715 x 867 x 286 x 638 = 113112825540
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.
715 : 1, 5, 11, 13, 55, 65, 143, 715
867 : 1, 3, 17, 51, 289, 867
286 : 1, 2, 11, 13, 22, 26, 143, 286
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 715,867,286,638, is 1.
Now, the common factors can be found like this.
715:5x 11x 13
867:3x 17x 17
286:2x 11x 13
638:2x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11x 13 = 3146
Therefore, the value for common factors is 3146.
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 = 113112825540/(1x3146)
LCM = 113112825540/3146
LCM = 35954490
Thus, we can understand that the LCM of 715,867,286,638 is 35954490.
