Given numbers are 242,578,682,391,658
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 242,578,682,391,658 is 16405846226.
Find LCM of 242,578,682,391,658 with Prime Factorization
| 2 | 242, 578, 682, 391, 658 |
| 11 | 121, 289, 341, 391, 329 |
| 17 | 11, 289, 31, 391, 329 |
| 11, 17, 31, 23, 329 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 17 x 11 x 17 x 31 x 23 x 329 = 16405846226
Therefore, the lowest common multiple of 242,578,682,391,658 is 16405846226.
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.
242 x 578 x 682 x 391 x 658 = 24543145954096
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.
242 : 1, 2, 11, 22, 121, 242
578 : 1, 2, 17, 34, 289, 578
682 : 1, 2, 11, 22, 31, 62, 341, 682
391 : 1, 17, 23, 391
658 : 1, 2, 7, 14, 47, 94, 329, 658
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 242,578,682,391,658, is 1.
Now, the common factors can be found like this.
242:2x 11x 11
578:2x 17x 17
682:2x 11x 31
391:17x 23
658:2x 7x 47
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 11x 17 = 1496
Therefore, the value for common factors is 1496.
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 = 24543145954096/(1x1496)
LCM = 24543145954096/1496
LCM = 16405846226
Thus, we can understand that the LCM of 242,578,682,391,658 is 16405846226.
