Given numbers are 440,641,810,724,843
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 440,641,810,724,843 is 1161931751640.
Find LCM of 440,641,810,724,843 with Prime Factorization
| 2 | 440, 641, 810, 724, 843 |
| 2 | 220, 641, 405, 362, 843 |
| 3 | 110, 641, 405, 181, 843 |
| 5 | 110, 641, 135, 181, 281 |
| 22, 641, 27, 181, 281 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 22 x 641 x 27 x 181 x 281 = 1161931751640
Therefore, the lowest common multiple of 440,641,810,724,843 is 1161931751640.
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 641 x 810 x 724 x 843 = 139431810196800
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
641 : 1, 641
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
724 : 1, 2, 4, 181, 362, 724
843 : 1, 3, 281, 843
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,641,810,724,843, is 1.
Now, the common factors can be found like this.
440:2x 2x 2x 5x 11
641:641
810:2x 3x 3x 3x 3x 5
724:2x 2x 181
843:3x 281
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 139431810196800/(1x120)
LCM = 139431810196800/120
LCM = 1161931751640
Thus, we can understand that the LCM of 440,641,810,724,843 is 1161931751640.
