Given numbers are 633,782,489,391,605
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 633,782,489,391,605 is 48815016690.
Find LCM of 633,782,489,391,605 with Prime Factorization
| 3 | 633, 782, 489, 391, 605 |
| 17 | 211, 782, 163, 391, 605 |
| 23 | 211, 46, 163, 23, 605 |
| 211, 2, 163, 1, 605 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 23 x 211 x 2 x 163 x 1 x 605 = 48815016690
Therefore, the lowest common multiple of 633,782,489,391,605 is 48815016690.
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.
633 x 782 x 489 x 391 x 605 = 57260014577370
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.
633 : 1, 3, 211, 633
782 : 1, 2, 17, 23, 34, 46, 391, 782
489 : 1, 3, 163, 489
391 : 1, 17, 23, 391
605 : 1, 5, 11, 55, 121, 605
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 633,782,489,391,605, is 1.
Now, the common factors can be found like this.
633:3x 211
782:2x 17x 23
489:3x 163
391:17x 23
605:5x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 17x 23 = 1173
Therefore, the value for common factors is 1173.
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 = 57260014577370/(1x1173)
LCM = 57260014577370/1173
LCM = 48815016690
Thus, we can understand that the LCM of 633,782,489,391,605 is 48815016690.
