Given numbers are 581,903,987,995
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 581,903,987,995 is 3504989985.
Find LCM of 581,903,987,995 with Prime Factorization
| 3 | 581, 903, 987, 995 |
| 7 | 581, 301, 329, 995 |
| 83, 43, 47, 995 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 83 x 43 x 47 x 995 = 3504989985
Therefore, the lowest common multiple of 581,903,987,995 is 3504989985.
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.
581 x 903 x 987 x 995 = 515233527795
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.
581 : 1, 7, 83, 581
903 : 1, 3, 7, 21, 43, 129, 301, 903
987 : 1, 3, 7, 21, 47, 141, 329, 987
995 : 1, 5, 199, 995
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 581,903,987,995, is 1.
Now, the common factors can be found like this.
581:7x 83
903:3x 7x 43
987:3x 7x 47
995:5x 199
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7 = 147
Therefore, the value for common factors is 147.
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 = 515233527795/(1x147)
LCM = 515233527795/147
LCM = 3504989985
Thus, we can understand that the LCM of 581,903,987,995 is 3504989985.
