Given numbers are 403,725,506,286,663
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,725,506,286,663 is 7539868050.
Find LCM of 403,725,506,286,663 with Prime Factorization
| 2 | 403, 725, 506, 286, 663 |
| 11 | 403, 725, 253, 143, 663 |
| 13 | 403, 725, 23, 13, 663 |
| 31, 725, 23, 1, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 13 x 31 x 725 x 23 x 1 x 51 = 7539868050
Therefore, the lowest common multiple of 403,725,506,286,663 is 7539868050.
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 725 x 506 x 286 x 663 = 28033229409900
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
725 : 1, 5, 25, 29, 145, 725
506 : 1, 2, 11, 22, 23, 46, 253, 506
286 : 1, 2, 11, 13, 22, 26, 143, 286
663 : 1, 3, 13, 17, 39, 51, 221, 663
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,725,506,286,663, is 1.
Now, the common factors can be found like this.
403:13x 31
725:5x 5x 29
506:2x 11x 23
286:2x 11x 13
663:3x 13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 13x 13 = 3718
Therefore, the value for common factors is 3718.
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 = 28033229409900/(1x3718)
LCM = 28033229409900/3718
LCM = 7539868050
Thus, we can understand that the LCM of 403,725,506,286,663 is 7539868050.
