The LCM of 321,709,663,799,351 is 21275702487.
Find LCM of 321,709,663,799,351 with Prime Factorization
| 3 | 321, 709, 663, 799, 351 |
| 13 | 107, 709, 221, 799, 117 |
| 17 | 107, 709, 17, 799, 9 |
| 107, 709, 1, 47, 9 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 17 x 107 x 709 x 1 x 47 x 9 = 21275702487
Therefore, the lowest common multiple of 321,709,663,799,351 is 21275702487.
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.
321 x 709 x 663 x 799 x 351 = 42317372246643
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.
321 : 1, 3, 107, 321
709 : 1, 709
663 : 1, 3, 13, 17, 39, 51, 221, 663
799 : 1, 17, 47, 799
351 : 1, 3, 9, 13, 27, 39, 117, 351
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,709,663,799,351, is 1.
Now, the common factors can be found like this.
321:3x 107
709:709
663:3x 13x 17
799:17x 47
351:3x 3x 3x 13
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 13x 17 = 1989
Therefore, the value for common factors is 1989.
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 = 42317372246643/(1x1989)
LCM = 42317372246643/1989
LCM = 21275702487
Thus, we can understand that the LCM of 321,709,663,799,351 is 21275702487.
