Find LCM of 654,136,432,906,457 with Prime Factorization
| 2 | 654, 136, 432, 906, 457 |
| 2 | 327, 68, 216, 453, 457 |
| 2 | 327, 34, 108, 453, 457 |
| 3 | 327, 17, 54, 453, 457 |
| 109, 17, 18, 151, 457 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 109 x 17 x 18 x 151 x 457 = 55239827472
Therefore, the lowest common multiple of 654,136,432,906,457 is 55239827472.
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.
654 x 136 x 432 x 906 x 457 = 15909070311936
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.
654 : 1, 2, 3, 6, 109, 218, 327, 654
136 : 1, 2, 4, 8, 17, 34, 68, 136
432 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 36, 48, 54, 72, 108, 144, 216, 432
906 : 1, 2, 3, 6, 151, 302, 453, 906
457 : 1, 457
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 654,136,432,906,457, is 1.
Now, the common factors can be found like this.
654:2x 3x 109
136:2x 2x 2x 17
432:2x 2x 2x 2x 3x 3x 3
906:2x 3x 151
457:457
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 3 = 288
Therefore, the value for common factors is 288.
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 = 15909070311936/(1x288)
LCM = 15909070311936/288
LCM = 55239827472
Thus, we can understand that the LCM of 654,136,432,906,457 is 55239827472.
