Given numbers are 579,526,921,280,691
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 579,526,921,280,691 is 9045004065720.
Find LCM of 579,526,921,280,691 with Prime Factorization
| 2 | 579, 526, 921, 280, 691 |
| 3 | 579, 263, 921, 140, 691 |
| 193, 263, 307, 140, 691 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 193 x 263 x 307 x 140 x 691 = 9045004065720
Therefore, the lowest common multiple of 579,526,921,280,691 is 9045004065720.
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.
579 x 526 x 921 x 280 x 691 = 54270024394320
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.
579 : 1, 3, 193, 579
526 : 1, 2, 263, 526
921 : 1, 3, 307, 921
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 579,526,921,280,691, is 1.
Now, the common factors can be found like this.
579:3x 193
526:2x 263
921:3x 307
280:2x 2x 2x 5x 7
691:691
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3 = 6
Therefore, the value for common factors is 6.
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 = 54270024394320/(1x6)
LCM = 54270024394320/6
LCM = 9045004065720
Thus, we can understand that the LCM of 579,526,921,280,691 is 9045004065720.
