Given numbers are 440,649,891,554
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 440,649,891,554 is 582464520.
Find LCM of 440,649,891,554 with Prime Factorization
| 2 | 440, 649, 891, 554 |
| 11 | 220, 649, 891, 277 |
| 20, 59, 81, 277 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 20 x 59 x 81 x 277 = 582464520
Therefore, the lowest common multiple of 440,649,891,554 is 582464520.
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 649 x 891 x 554 = 140956413840
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
649 : 1, 11, 59, 649
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
554 : 1, 2, 277, 554
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,649,891,554, is 1.
Now, the common factors can be found like this.
440:2x 2x 2x 5x 11
649:11x 59
891:3x 3x 3x 3x 11
554:2x 277
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 11x 11 = 242
Therefore, the value for common factors is 242.
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 = 140956413840/(1x242)
LCM = 140956413840/242
LCM = 582464520
Thus, we can understand that the LCM of 440,649,891,554 is 582464520.
