The LCM of 479,621,891,715 is 638049555.
Find LCM of 479,621,891,715 with Prime Factorization
| 3 | 479, 621, 891, 715 |
| 3 | 479, 207, 297, 715 |
| 3 | 479, 69, 99, 715 |
| 11 | 479, 23, 33, 715 |
| 479, 23, 3, 65 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 11 x 479 x 23 x 3 x 65 = 638049555
Therefore, the lowest common multiple of 479,621,891,715 is 638049555.
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.
479 x 621 x 891 x 715 = 189500717835
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.
479 : 1, 479
621 : 1, 3, 9, 23, 27, 69, 207, 621
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 479,621,891,715, is 1.
Now, the common factors can be found like this.
479:479
621:3x 3x 3x 23
891:3x 3x 3x 3x 11
715:5x 11x 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 3x 11 = 297
Therefore, the value for common factors is 297.
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 = 189500717835/(1x297)
LCM = 189500717835/297
LCM = 638049555
Thus, we can understand that the LCM of 479,621,891,715 is 638049555.
