Given numbers are 581,731,909,721,936
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 581,731,909,721,936 is 4135499346888.
Find LCM of 581,731,909,721,936 with Prime Factorization
| 3 | 581, 731, 909, 721, 936 |
| 3 | 581, 731, 303, 721, 312 |
| 7 | 581, 731, 101, 721, 104 |
| 83, 731, 101, 103, 104 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 83 x 731 x 101 x 103 x 104 = 4135499346888
Therefore, the lowest common multiple of 581,731,909,721,936 is 4135499346888.
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 731 x 909 x 721 x 936 = 260536458853944
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
731 : 1, 17, 43, 731
909 : 1, 3, 9, 101, 303, 909
721 : 1, 7, 103, 721
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 581,731,909,721,936, is 1.
Now, the common factors can be found like this.
581:7x 83
731:17x 43
909:3x 3x 101
721:7x 103
936:2x 2x 2x 3x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 7 = 63
Therefore, the value for common factors is 63.
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 = 260536458853944/(1x63)
LCM = 260536458853944/63
LCM = 4135499346888
Thus, we can understand that the LCM of 581,731,909,721,936 is 4135499346888.
