Find LCM of 645,469,954,685,371 with Prime Factorization
| 3 | 645, 469, 954, 685, 371 |
| 5 | 215, 469, 318, 685, 371 |
| 7 | 43, 469, 318, 137, 371 |
| 53 | 43, 67, 318, 137, 53 |
| 43, 67, 6, 137, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 53 x 43 x 67 x 6 x 137 x 1 = 13178932830
Therefore, the lowest common multiple of 645,469,954,685,371 is 13178932830.
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.
645 x 469 x 954 x 685 x 371 = 73340761198950
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.
645 : 1, 3, 5, 15, 43, 129, 215, 645
469 : 1, 7, 67, 469
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
685 : 1, 5, 137, 685
371 : 1, 7, 53, 371
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 645,469,954,685,371, is 1.
Now, the common factors can be found like this.
645:3x 5x 43
469:7x 67
954:2x 3x 3x 53
685:5x 137
371:7x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 7x 53 = 5565
Therefore, the value for common factors is 5565.
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 = 73340761198950/(1x5565)
LCM = 73340761198950/5565
LCM = 13178932830
Thus, we can understand that the LCM of 645,469,954,685,371 is 13178932830.
