Given numbers are 396,436,523,172,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 396,436,523,172,989 is 22326449508.
Find LCM of 396,436,523,172,989 with Prime Factorization
| 2 | 396, 436, 523, 172, 989 |
| 2 | 198, 218, 523, 86, 989 |
| 43 | 99, 109, 523, 43, 989 |
| 99, 109, 523, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 99 x 109 x 523 x 1 x 23 = 22326449508
Therefore, the lowest common multiple of 396,436,523,172,989 is 22326449508.
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.
396 x 436 x 523 x 172 x 989 = 15360597261504
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.
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
436 : 1, 2, 4, 109, 218, 436
523 : 1, 523
172 : 1, 2, 4, 43, 86, 172
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,436,523,172,989, is 1.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
436:2x 2x 109
523:523
172:2x 2x 43
989:23x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 43 = 688
Therefore, the value for common factors is 688.
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 = 15360597261504/(1x688)
LCM = 15360597261504/688
LCM = 22326449508
Thus, we can understand that the LCM of 396,436,523,172,989 is 22326449508.
