Given numbers are 381,964,491,286
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 381,964,491,286 is 25788111492.
Find LCM of 381,964,491,286 with Prime Factorization
| 2 | 381, 964, 491, 286 |
| 381, 482, 491, 143 |
Multiply the prime numbers at the bottom and the left side.
2 x 381 x 482 x 491 x 143 = 25788111492
Therefore, the lowest common multiple of 381,964,491,286 is 25788111492.
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.
381 x 964 x 491 x 286 = 51576222984
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.
381 : 1, 3, 127, 381
964 : 1, 2, 4, 241, 482, 964
491 : 1, 491
286 : 1, 2, 11, 13, 22, 26, 143, 286
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 381,964,491,286, is 1.
Now, the common factors can be found like this.
381:3x 127
964:2x 2x 241
491:491
286:2x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 51576222984/(1x2)
LCM = 51576222984/2
LCM = 25788111492
Thus, we can understand that the LCM of 381,964,491,286 is 25788111492.
