Given numbers are 501,639,684,755,920
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 501,639,684,755,920 is 281666829240.
Find LCM of 501,639,684,755,920 with Prime Factorization
| 2 | 501, 639, 684, 755, 920 |
| 2 | 501, 639, 342, 755, 460 |
| 3 | 501, 639, 171, 755, 230 |
| 3 | 167, 213, 57, 755, 230 |
| 5 | 167, 71, 19, 755, 230 |
| 167, 71, 19, 151, 46 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 167 x 71 x 19 x 151 x 46 = 281666829240
Therefore, the lowest common multiple of 501,639,684,755,920 is 281666829240.
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.
501 x 639 x 684 x 755 x 920 = 152100087789600
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.
501 : 1, 3, 167, 501
639 : 1, 3, 9, 71, 213, 639
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
755 : 1, 5, 151, 755
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 501,639,684,755,920, is 1.
Now, the common factors can be found like this.
501:3x 167
639:3x 3x 71
684:2x 2x 3x 3x 19
755:5x 151
920:2x 2x 2x 5x 23
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 3x 3x 3x 5 = 540
Therefore, the value for common factors is 540.
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 = 152100087789600/(1x540)
LCM = 152100087789600/540
LCM = 281666829240
Thus, we can understand that the LCM of 501,639,684,755,920 is 281666829240.
