Given numbers are 403,872,731,501,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,872,731,501,642 is 13770839341272.
Find LCM of 403,872,731,501,642 with Prime Factorization
2 | 403, 872, 731, 501, 642 |
3 | 403, 436, 731, 501, 321 |
403, 436, 731, 167, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 403 x 436 x 731 x 167 x 107 = 13770839341272
Therefore, the lowest common multiple of 403,872,731,501,642 is 13770839341272.
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 872 x 731 x 501 x 642 = 82625036047632
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
872 : 1, 2, 4, 8, 109, 218, 436, 872
731 : 1, 17, 43, 731
501 : 1, 3, 167, 501
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,872,731,501,642, is 1.
Now, the common factors can be found like this.
403:13x 31
872:2x 2x 2x 109
731:17x 43
501:3x 167
642:2x 3x 107
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 = 82625036047632/(1x6)
LCM = 82625036047632/6
LCM = 13770839341272
Thus, we can understand that the LCM of 403,872,731,501,642 is 13770839341272.
