Find LCM of 399,328,276,551,128 with Prime Factorization
| 2 | 399, 328, 276, 551, 128 |
| 2 | 399, 164, 138, 551, 64 |
| 2 | 399, 82, 69, 551, 32 |
| 3 | 399, 41, 69, 551, 16 |
| 19 | 133, 41, 23, 551, 16 |
| 7, 41, 23, 29, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 19 x 7 x 41 x 23 x 29 x 16 = 1396665984
Therefore, the lowest common multiple of 399,328,276,551,128 is 1396665984.
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.
399 x 328 x 276 x 551 x 128 = 2547518754816
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.
399 : 1, 3, 7, 19, 21, 57, 133, 399
328 : 1, 2, 4, 8, 41, 82, 164, 328
276 : 1, 2, 3, 4, 6, 12, 23, 46, 69, 92, 138, 276
551 : 1, 19, 29, 551
128 : 1, 2, 4, 8, 16, 32, 64, 128
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,328,276,551,128, is 1.
Now, the common factors can be found like this.
399:3x 7x 19
328:2x 2x 2x 41
276:2x 2x 3x 23
551:19x 29
128:2x 2x 2x 2x 2x 2x 2
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 3x 19 = 1824
Therefore, the value for common factors is 1824.
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 = 2547518754816/(1x1824)
LCM = 2547518754816/1824
LCM = 1396665984
Thus, we can understand that the LCM of 399,328,276,551,128 is 1396665984.
