Find LCM of 906,903,755,457,645 with Prime Factorization
| 3 | 906, 903, 755, 457, 645 |
| 5 | 302, 301, 755, 457, 215 |
| 43 | 302, 301, 151, 457, 43 |
| 151 | 302, 7, 151, 457, 1 |
| 2, 7, 1, 457, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 43 x 151 x 2 x 7 x 1 x 457 x 1 = 623133210
Therefore, the lowest common multiple of 906,903,755,457,645 is 623133210.
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.
906 x 903 x 755 x 457 x 645 = 182070176963850
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.
906 : 1, 2, 3, 6, 151, 302, 453, 906
903 : 1, 3, 7, 21, 43, 129, 301, 903
755 : 1, 5, 151, 755
457 : 1, 457
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 906,903,755,457,645, is 1.
Now, the common factors can be found like this.
906:2x 3x 151
903:3x 7x 43
755:5x 151
457:457
645:3x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 43x 151 = 292185
Therefore, the value for common factors is 292185.
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 = 182070176963850/(1x292185)
LCM = 182070176963850/292185
LCM = 623133210
Thus, we can understand that the LCM of 906,903,755,457,645 is 623133210.
