Given numbers are 440,401,806
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 440,401,806 is 71105320.
Find LCM of 440,401,806 with Prime Factorization
| 2 | 440, 401, 806 |
| 220, 401, 403 |
Multiply the prime numbers at the bottom and the left side.
2 x 220 x 401 x 403 = 71105320
Therefore, the lowest common multiple of 440,401,806 is 71105320.
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.
440 x 401 x 806 = 142210640
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.
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
401 : 1, 401
806 : 1, 2, 13, 26, 31, 62, 403, 806
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,401,806, is 1.
Now, the common factors can be found like this.
440:2x 2x 2x 5x 11
401:401
806:2x 13x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 142210640/(1x2)
LCM = 142210640/2
LCM = 71105320
Thus, we can understand that the LCM of 440,401,806 is 71105320.
