Find LCM of 945,585,730,671,397 with Prime Factorization
| 3 | 945, 585, 730, 671, 397 |
| 3 | 315, 195, 730, 671, 397 |
| 5 | 105, 65, 730, 671, 397 |
| 21, 13, 146, 671, 397 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 21 x 13 x 146 x 671 x 397 = 477794387070
Therefore, the lowest common multiple of 945,585,730,671,397 is 477794387070.
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.
945 x 585 x 730 x 671 x 397 = 107503737090750
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.
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
730 : 1, 2, 5, 10, 73, 146, 365, 730
671 : 1, 11, 61, 671
397 : 1, 397
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 945,585,730,671,397, is 1.
Now, the common factors can be found like this.
945:3x 3x 3x 5x 7
585:3x 3x 5x 13
730:2x 5x 73
671:11x 61
397:397
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 5 = 225
Therefore, the value for common factors is 225.
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 = 107503737090750/(1x225)
LCM = 107503737090750/225
LCM = 477794387070
Thus, we can understand that the LCM of 945,585,730,671,397 is 477794387070.
