Find LCM of 900,891,704,440 with Prime Factorization
| 2 | 900, 891, 704, 440 |
| 2 | 450, 891, 352, 220 |
| 2 | 225, 891, 176, 110 |
| 3 | 225, 891, 88, 55 |
| 3 | 75, 297, 88, 55 |
| 5 | 25, 99, 88, 55 |
| 11 | 5, 99, 88, 11 |
| 5, 9, 8, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 11 x 5 x 9 x 8 x 1 = 1425600
Therefore, the lowest common multiple of 900,891,704,440 is 1425600.
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.
900 x 891 x 704 x 440 = 248396544000
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.
900 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 25, 30, 36, 45, 50, 60, 75, 90, 100, 150, 180, 225, 300, 450, 900
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 900,891,704,440, is 1.
Now, the common factors can be found like this.
900:2x 2x 3x 3x 5x 5
891:3x 3x 3x 3x 11
704:2x 2x 2x 2x 2x 2x 11
440:2x 2x 2x 5x 11
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 3x 3x 5x 11x 11 = 174240
Therefore, the value for common factors is 174240.
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 = 248396544000/(1x174240)
LCM = 248396544000/174240
LCM = 1425600
Thus, we can understand that the LCM of 900,891,704,440 is 1425600.
