Given numbers are 440,825,869,801
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 440,825,869,801 is 139213800.
Find LCM of 440,825,869,801 with Prime Factorization
| 3 | 440, 825, 869, 801 |
| 5 | 440, 275, 869, 267 |
| 11 | 88, 55, 869, 267 |
| 8, 5, 79, 267 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 11 x 8 x 5 x 79 x 267 = 139213800
Therefore, the lowest common multiple of 440,825,869,801 is 139213800.
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 825 x 869 x 801 = 252673047000
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
825 : 1, 3, 5, 11, 15, 25, 33, 55, 75, 165, 275, 825
869 : 1, 11, 79, 869
801 : 1, 3, 9, 89, 267, 801
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,825,869,801, is 1.
Now, the common factors can be found like this.
440:2x 2x 2x 5x 11
825:3x 5x 5x 11
869:11x 79
801:3x 3x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 11x 11 = 1815
Therefore, the value for common factors is 1815.
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 = 252673047000/(1x1815)
LCM = 252673047000/1815
LCM = 139213800
Thus, we can understand that the LCM of 440,825,869,801 is 139213800.
