Given numbers are 440,985,920,460,505
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 440,985,920,460,505 is 201357640.
Find LCM of 440,985,920,460,505 with Prime Factorization
| 2 | 440, 985, 920, 460, 505 |
| 2 | 220, 985, 460, 230, 505 |
| 2 | 110, 985, 115, 230, 505 |
| 5 | 55, 985, 115, 115, 505 |
| 23 | 11, 197, 23, 23, 101 |
| 11, 197, 1, 1, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 23 x 11 x 197 x 1 x 1 x 101 = 201357640
Therefore, the lowest common multiple of 440,985,920,460,505 is 201357640.
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.
440 x 985 x 920 x 460 x 505 = 92624514400000
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.
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
985 : 1, 5, 197, 985
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
505 : 1, 5, 101, 505
5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,985,920,460,505, is 5.
Now, the common factors can be found like this.
440:2x 2x 2x 5x 11
985:5x 197
920:2x 2x 2x 5x 23
460:2x 2x 5x 23
505:5x 101
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 5x 5x 5x 23 = 92000
Therefore, the value for common factors is 92000.
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 = 92624514400000/(5x92000)
LCM = 92624514400000/460000
LCM = 201357640
Thus, we can understand that the LCM of 440,985,920,460,505 is 201357640.
