Given numbers are 403,873,394,654
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,873,394,654 is 15109218774.
Find LCM of 403,873,394,654 with Prime Factorization
| 2 | 403, 873, 394, 654 |
| 3 | 403, 873, 197, 327 |
| 403, 291, 197, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 403 x 291 x 197 x 109 = 15109218774
Therefore, the lowest common multiple of 403,873,394,654 is 15109218774.
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.
403 x 873 x 394 x 654 = 90655312644
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.
403 : 1, 13, 31, 403
873 : 1, 3, 9, 97, 291, 873
394 : 1, 2, 197, 394
654 : 1, 2, 3, 6, 109, 218, 327, 654
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,873,394,654, is 1.
Now, the common factors can be found like this.
403:13x 31
873:3x 3x 97
394:2x 197
654:2x 3x 109
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 = 90655312644/(1x6)
LCM = 90655312644/6
LCM = 15109218774
Thus, we can understand that the LCM of 403,873,394,654 is 15109218774.
