Given numbers are 278,758,730,255,768
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,758,730,255,768 is 251048144640.
Find LCM of 278,758,730,255,768 with Prime Factorization
| 2 | 278, 758, 730, 255, 768 |
| 3 | 139, 379, 365, 255, 384 |
| 5 | 139, 379, 365, 85, 128 |
| 139, 379, 73, 17, 128 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 139 x 379 x 73 x 17 x 128 = 251048144640
Therefore, the lowest common multiple of 278,758,730,255,768 is 251048144640.
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.
278 x 758 x 730 x 255 x 768 = 30125777356800
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.
278 : 1, 2, 139, 278
758 : 1, 2, 379, 758
730 : 1, 2, 5, 10, 73, 146, 365, 730
255 : 1, 3, 5, 15, 17, 51, 85, 255
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,758,730,255,768, is 1.
Now, the common factors can be found like this.
278:2x 139
758:2x 379
730:2x 5x 73
255:3x 5x 17
768:2x 2x 2x 2x 2x 2x 2x 2x 3
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 30125777356800/(1x120)
LCM = 30125777356800/120
LCM = 251048144640
Thus, we can understand that the LCM of 278,758,730,255,768 is 251048144640.
