Given numbers are 486,658,221,587
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 486,658,221,587 is 20742568938.
Find LCM of 486,658,221,587 with Prime Factorization
| 2 | 486, 658, 221, 587 |
| 243, 329, 221, 587 |
Multiply the prime numbers at the bottom and the left side.
2 x 243 x 329 x 221 x 587 = 20742568938
Therefore, the lowest common multiple of 486,658,221,587 is 20742568938.
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.
486 x 658 x 221 x 587 = 41485137876
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.
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
658 : 1, 2, 7, 14, 47, 94, 329, 658
221 : 1, 13, 17, 221
587 : 1, 587
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 486,658,221,587, is 1.
Now, the common factors can be found like this.
486:2x 3x 3x 3x 3x 3
658:2x 7x 47
221:13x 17
587:587
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 41485137876/(1x2)
LCM = 41485137876/2
LCM = 20742568938
Thus, we can understand that the LCM of 486,658,221,587 is 20742568938.
