Given numbers are 278,978,216,860,768
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,978,216,860,768 is 33670114560.
Find LCM of 278,978,216,860,768 with Prime Factorization
| 2 | 278, 978, 216, 860, 768 |
| 2 | 139, 489, 108, 430, 384 |
| 2 | 139, 489, 54, 215, 192 |
| 3 | 139, 489, 27, 215, 96 |
| 139, 163, 9, 215, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 139 x 163 x 9 x 215 x 32 = 33670114560
Therefore, the lowest common multiple of 278,978,216,860,768 is 33670114560.
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 978 x 216 x 860 x 768 = 38787971973120
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
978 : 1, 2, 3, 6, 163, 326, 489, 978
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,978,216,860,768, is 2.
Now, the common factors can be found like this.
278:2x 139
978:2x 3x 163
216:2x 2x 2x 3x 3x 3
860:2x 2x 5x 43
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 2x 2x 2x 3x 3 = 576
Therefore, the value for common factors is 576.
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 = 38787971973120/(2x576)
LCM = 38787971973120/1152
LCM = 33670114560
Thus, we can understand that the LCM of 278,978,216,860,768 is 33670114560.
