Find LCM of 648,571,800,920,294 with Prime Factorization
| 2 | 648, 571, 800, 920, 294 |
| 2 | 324, 571, 400, 460, 147 |
| 2 | 162, 571, 200, 230, 147 |
| 3 | 81, 571, 100, 115, 147 |
| 5 | 27, 571, 100, 115, 49 |
| 27, 571, 20, 23, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 27 x 571 x 20 x 23 x 49 = 41699901600
Therefore, the lowest common multiple of 648,571,800,920,294 is 41699901600.
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.
648 x 571 x 800 x 920 x 294 = 80063811072000
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.
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
571 : 1, 571
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
294 : 1, 2, 3, 6, 7, 14, 21, 42, 49, 98, 147, 294
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,571,800,920,294, is 1.
Now, the common factors can be found like this.
648:2x 2x 2x 3x 3x 3x 3
571:571
800:2x 2x 2x 2x 2x 5x 5
920:2x 2x 2x 5x 23
294:2x 3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 2x 2x 2x 2x 3x 5 = 1920
Therefore, the value for common factors is 1920.
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 = 80063811072000/(1x1920)
LCM = 80063811072000/1920
LCM = 41699901600
Thus, we can understand that the LCM of 648,571,800,920,294 is 41699901600.
