Find LCM of 313,943,747,554,621 with Prime Factorization
| 3 | 313, 943, 747, 554, 621 |
| 3 | 313, 943, 249, 554, 207 |
| 23 | 313, 943, 83, 554, 69 |
| 313, 41, 83, 554, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 23 x 313 x 41 x 83 x 554 x 3 = 366444030726
Therefore, the lowest common multiple of 313,943,747,554,621 is 366444030726.
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.
313 x 943 x 747 x 554 x 621 = 75853914360282
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.
313 : 1, 313
943 : 1, 23, 41, 943
747 : 1, 3, 9, 83, 249, 747
554 : 1, 2, 277, 554
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 313,943,747,554,621, is 1.
Now, the common factors can be found like this.
313:313
943:23x 41
747:3x 3x 83
554:2x 277
621:3x 3x 3x 23
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 23 = 207
Therefore, the value for common factors is 207.
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 = 75853914360282/(1x207)
LCM = 75853914360282/207
LCM = 366444030726
Thus, we can understand that the LCM of 313,943,747,554,621 is 366444030726.
