Given numbers are 396,391,551,196
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 396,391,551,196 is 4180417164.
Find LCM of 396,391,551,196 with Prime Factorization
| 2 | 396, 391, 551, 196 |
| 2 | 198, 391, 551, 98 |
| 99, 391, 551, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 99 x 391 x 551 x 49 = 4180417164
Therefore, the lowest common multiple of 396,391,551,196 is 4180417164.
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 391 x 551 x 196 = 16721668656
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
391 : 1, 17, 23, 391
551 : 1, 19, 29, 551
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 396,391,551,196, is 1.
Now, the common factors can be found like this.
396:2x 2x 3x 3x 11
391:17x 23
551:19x 29
196:2x 2x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 16721668656/(1x4)
LCM = 16721668656/4
LCM = 4180417164
Thus, we can understand that the LCM of 396,391,551,196 is 4180417164.
