Given numbers are 574,273,396,554,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 574,273,396,554,642 is 43790911164.
Find LCM of 574,273,396,554,642 with Prime Factorization
| 2 | 574, 273, 396, 554, 642 |
| 3 | 287, 273, 198, 277, 321 |
| 7 | 287, 91, 66, 277, 107 |
| 41, 13, 66, 277, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 41 x 13 x 66 x 277 x 107 = 43790911164
Therefore, the lowest common multiple of 574,273,396,554,642 is 43790911164.
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.
574 x 273 x 396 x 554 x 642 = 22070619226656
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.
574 : 1, 2, 7, 14, 41, 82, 287, 574
273 : 1, 3, 7, 13, 21, 39, 91, 273
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
554 : 1, 2, 277, 554
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 574,273,396,554,642, is 1.
Now, the common factors can be found like this.
574:2x 7x 41
273:3x 7x 13
396:2x 2x 3x 3x 11
554:2x 277
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 3x 7 = 504
Therefore, the value for common factors is 504.
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 = 22070619226656/(1x504)
LCM = 22070619226656/504
LCM = 43790911164
Thus, we can understand that the LCM of 574,273,396,554,642 is 43790911164.
