Given numbers are 885,456,286,397
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 885,456,286,397 is 7636834920.
Find LCM of 885,456,286,397 with Prime Factorization
| 2 | 885, 456, 286, 397 |
| 3 | 885, 228, 143, 397 |
| 295, 76, 143, 397 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 295 x 76 x 143 x 397 = 7636834920
Therefore, the lowest common multiple of 885,456,286,397 is 7636834920.
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.
885 x 456 x 286 x 397 = 45821009520
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.
885 : 1, 3, 5, 15, 59, 177, 295, 885
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
286 : 1, 2, 11, 13, 22, 26, 143, 286
397 : 1, 397
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 885,456,286,397, is 1.
Now, the common factors can be found like this.
885:3x 5x 59
456:2x 2x 2x 3x 19
286:2x 11x 13
397:397
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 45821009520/(1x6)
LCM = 45821009520/6
LCM = 7636834920
Thus, we can understand that the LCM of 885,456,286,397 is 7636834920.
