Given numbers are 813,783,899,173
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 813,783,899,173 is 1137991059.
Find LCM of 813,783,899,173 with Prime Factorization
| 3 | 813, 783, 899, 173 |
| 29 | 271, 261, 899, 173 |
| 271, 9, 31, 173 |
Multiply the prime numbers at the bottom and the left side.
3 x 29 x 271 x 9 x 31 x 173 = 1137991059
Therefore, the lowest common multiple of 813,783,899,173 is 1137991059.
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.
813 x 783 x 899 x 173 = 99005222133
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.
813 : 1, 3, 271, 813
783 : 1, 3, 9, 27, 29, 87, 261, 783
899 : 1, 29, 31, 899
173 : 1, 173
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 813,783,899,173, is 1.
Now, the common factors can be found like this.
813:3x 271
783:3x 3x 3x 29
899:29x 31
173:173
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 29 = 87
Therefore, the value for common factors is 87.
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 = 99005222133/(1x87)
LCM = 99005222133/87
LCM = 1137991059
Thus, we can understand that the LCM of 813,783,899,173 is 1137991059.
