Given numbers are 260,581,665,401
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 260,581,665,401 is 1150926140.
Find LCM of 260,581,665,401 with Prime Factorization
| 5 | 260, 581, 665, 401 |
| 7 | 52, 581, 133, 401 |
| 52, 83, 19, 401 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 52 x 83 x 19 x 401 = 1150926140
Therefore, the lowest common multiple of 260,581,665,401 is 1150926140.
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.
260 x 581 x 665 x 401 = 40282414900
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.
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
581 : 1, 7, 83, 581
665 : 1, 5, 7, 19, 35, 95, 133, 665
401 : 1, 401
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 260,581,665,401, is 1.
Now, the common factors can be found like this.
260:2x 2x 5x 13
581:7x 83
665:5x 7x 19
401:401
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7 = 35
Therefore, the value for common factors is 35.
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 = 40282414900/(1x35)
LCM = 40282414900/35
LCM = 1150926140
Thus, we can understand that the LCM of 260,581,665,401 is 1150926140.
