Given numbers are 403,781,363,213
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,781,363,213 is 10386519.
Find LCM of 403,781,363,213 with Prime Factorization
| 3 | 403, 781, 363, 213 |
| 11 | 403, 781, 121, 71 |
| 71 | 403, 71, 11, 71 |
| 403, 1, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 71 x 403 x 1 x 11 x 1 = 10386519
Therefore, the lowest common multiple of 403,781,363,213 is 10386519.
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 781 x 363 x 213 = 24335614017
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
781 : 1, 11, 71, 781
363 : 1, 3, 11, 33, 121, 363
213 : 1, 3, 71, 213
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,781,363,213, is 1.
Now, the common factors can be found like this.
403:13x 31
781:11x 71
363:3x 11x 11
213:3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 11x 71 = 2343
Therefore, the value for common factors is 2343.
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 = 24335614017/(1x2343)
LCM = 24335614017/2343
LCM = 10386519
Thus, we can understand that the LCM of 403,781,363,213 is 10386519.
