Given numbers are 884,637,391,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 884,637,391,871 is 66749956.
Find LCM of 884,637,391,871 with Prime Factorization
| 13 | 884, 637, 391, 871 |
| 17 | 68, 49, 391, 67 |
| 4, 49, 23, 67 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 4 x 49 x 23 x 67 = 66749956
Therefore, the lowest common multiple of 884,637,391,871 is 66749956.
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.
884 x 637 x 391 x 871 = 191772623588
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.
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
637 : 1, 7, 13, 49, 91, 637
391 : 1, 17, 23, 391
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 884,637,391,871, is 1.
Now, the common factors can be found like this.
884:2x 2x 13x 17
637:7x 7x 13
391:17x 23
871:13x 67
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 13x 17 = 2873
Therefore, the value for common factors is 2873.
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 = 191772623588/(1x2873)
LCM = 191772623588/2873
LCM = 66749956
Thus, we can understand that the LCM of 884,637,391,871 is 66749956.
