Given numbers are 558,721,396,716
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 558,721,396,716 is 1584328284.
Find LCM of 558,721,396,716 with Prime Factorization
| 2 | 558, 721, 396, 716 |
| 2 | 279, 721, 198, 358 |
| 3 | 279, 721, 99, 179 |
| 3 | 93, 721, 33, 179 |
| 31, 721, 11, 179 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 31 x 721 x 11 x 179 = 1584328284
Therefore, the lowest common multiple of 558,721,396,716 is 1584328284.
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.
558 x 721 x 396 x 716 = 114071636448
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.
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
721 : 1, 7, 103, 721
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
716 : 1, 2, 4, 179, 358, 716
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 558,721,396,716, is 1.
Now, the common factors can be found like this.
558:2x 3x 3x 31
721:7x 103
396:2x 2x 3x 3x 11
716:2x 2x 179
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 3 = 72
Therefore, the value for common factors is 72.
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 = 114071636448/(1x72)
LCM = 114071636448/72
LCM = 1584328284
Thus, we can understand that the LCM of 558,721,396,716 is 1584328284.
