Find LCM of 409,297,648,856 with Prime Factorization
| 2 | 409, 297, 648, 856 |
| 2 | 409, 297, 324, 428 |
| 2 | 409, 297, 162, 214 |
| 3 | 409, 297, 81, 107 |
| 3 | 409, 99, 27, 107 |
| 3 | 409, 33, 9, 107 |
| 409, 11, 3, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 3 x 409 x 11 x 3 x 107 = 311942664
Therefore, the lowest common multiple of 409,297,648,856 is 311942664.
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.
409 x 297 x 648 x 856 = 67379615424
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.
409 : 1, 409
297 : 1, 3, 9, 11, 27, 33, 99, 297
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,297,648,856, is 1.
Now, the common factors can be found like this.
409:409
297:3x 3x 3x 11
648:2x 2x 2x 3x 3x 3x 3
856:2x 2x 2x 107
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 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 67379615424/(1x216)
LCM = 67379615424/216
LCM = 311942664
Thus, we can understand that the LCM of 409,297,648,856 is 311942664.
