Given numbers are 319,668,253,920,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 319,668,253,920,638 is 49011160.
Find LCM of 319,668,253,920,638 with Prime Factorization
| 2 | 319, 668, 253, 920, 638 |
| 2 | 319, 334, 253, 460, 319 |
| 11 | 319, 167, 253, 230, 319 |
| 23 | 29, 167, 23, 230, 29 |
| 29 | 29, 167, 1, 10, 29 |
| 1, 167, 1, 10, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 23 x 29 x 1 x 167 x 1 x 10 x 1 = 49011160
Therefore, the lowest common multiple of 319,668,253,920,638 is 49011160.
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.
319 x 668 x 253 x 920 x 638 = 31644349520960
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.
319 : 1, 11, 29, 319
668 : 1, 2, 4, 167, 334, 668
253 : 1, 11, 23, 253
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 319,668,253,920,638, is 1.
Now, the common factors can be found like this.
319:11x 29
668:2x 2x 167
253:11x 23
920:2x 2x 2x 5x 23
638:2x 11x 29
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 11x 23x 29 = 645656
Therefore, the value for common factors is 645656.
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 = 31644349520960/(1x645656)
LCM = 31644349520960/645656
LCM = 49011160
Thus, we can understand that the LCM of 319,668,253,920,638 is 49011160.
