Find LCM of 231,256,638,432,354 with Prime Factorization
2 | 231, 256, 638, 432, 354 |
2 | 231, 128, 319, 216, 177 |
2 | 231, 64, 319, 108, 177 |
2 | 231, 32, 319, 54, 177 |
3 | 231, 16, 319, 27, 177 |
11 | 77, 16, 319, 9, 59 |
7, 16, 29, 9, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 11 x 7 x 16 x 29 x 9 x 59 = 910635264
Therefore, the lowest common multiple of 231,256,638,432,354 is 910635264.
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.
231 x 256 x 638 x 432 x 354 = 5769785032704
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.
231 : 1, 3, 7, 11, 21, 33, 77, 231
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
638 : 1, 2, 11, 22, 29, 58, 319, 638
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
354 : 1, 2, 3, 6, 59, 118, 177, 354
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 231,256,638,432,354, is 1.
Now, the common factors can be found like this.
231:3x 7x 11
256:2x 2x 2x 2x 2x 2x 2x 2
638:2x 11x 29
432:2x 2x 2x 2x 3x 3x 3
354:2x 3x 59
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 3x 11 = 6336
Therefore, the value for common factors is 6336.
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 = 5769785032704/(1x6336)
LCM = 5769785032704/6336
LCM = 910635264
Thus, we can understand that the LCM of 231,256,638,432,354 is 910635264.
