Find LCM of 288,278,649,648 with Prime Factorization
| 2 | 288, 278, 649, 648 |
| 2 | 144, 139, 649, 324 |
| 2 | 72, 139, 649, 162 |
| 3 | 36, 139, 649, 81 |
| 3 | 12, 139, 649, 27 |
| 4, 139, 649, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 4 x 139 x 649 x 9 = 233826912
Therefore, the lowest common multiple of 288,278,649,648 is 233826912.
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.
288 x 278 x 649 x 648 = 33671075328
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.
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
278 : 1, 2, 139, 278
649 : 1, 11, 59, 649
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 288,278,649,648, is 1.
Now, the common factors can be found like this.
288:2x 2x 2x 2x 2x 3x 3
278:2x 139
649:11x 59
648:2x 2x 2x 3x 3x 3x 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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 33671075328/(1x144)
LCM = 33671075328/144
LCM = 233826912
Thus, we can understand that the LCM of 288,278,649,648 is 233826912.
