Given numbers are 631,806,203,403
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 631,806,203,403 is 103242958.
Find LCM of 631,806,203,403 with Prime Factorization
| 13 | 631, 806, 203, 403 |
| 31 | 631, 62, 203, 31 |
| 631, 2, 203, 1 |
Multiply the prime numbers at the bottom and the left side.
13 x 31 x 631 x 2 x 203 x 1 = 103242958
Therefore, the lowest common multiple of 631,806,203,403 is 103242958.
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.
631 x 806 x 203 x 403 = 41606912074
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.
631 : 1, 631
806 : 1, 2, 13, 26, 31, 62, 403, 806
203 : 1, 7, 29, 203
403 : 1, 13, 31, 403
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,806,203,403, is 1.
Now, the common factors can be found like this.
631:631
806:2x 13x 31
203:7x 29
403:13x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 31 = 403
Therefore, the value for common factors is 403.
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 = 41606912074/(1x403)
LCM = 41606912074/403
LCM = 103242958
Thus, we can understand that the LCM of 631,806,203,403 is 103242958.
