Given numbers are 949,286,436,891
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 949,286,436,891 is 368663724.
Find LCM of 949,286,436,891 with Prime Factorization
| 2 | 949, 286, 436, 891 |
| 11 | 949, 143, 218, 891 |
| 13 | 949, 13, 218, 81 |
| 73, 1, 218, 81 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 73 x 1 x 218 x 81 = 368663724
Therefore, the lowest common multiple of 949,286,436,891 is 368663724.
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.
949 x 286 x 436 x 891 = 105437825064
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.
949 : 1, 13, 73, 949
286 : 1, 2, 11, 13, 22, 26, 143, 286
436 : 1, 2, 4, 109, 218, 436
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 949,286,436,891, is 1.
Now, the common factors can be found like this.
949:13x 73
286:2x 11x 13
436:2x 2x 109
891:3x 3x 3x 3x 11
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 13 = 286
Therefore, the value for common factors is 286.
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 = 105437825064/(1x286)
LCM = 105437825064/286
LCM = 368663724
Thus, we can understand that the LCM of 949,286,436,891 is 368663724.
