Given numbers are 723,420,469,810,575
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 723,420,469,810,575 is 21057302700.
Find LCM of 723,420,469,810,575 with Prime Factorization
| 2 | 723, 420, 469, 810, 575 |
| 3 | 723, 210, 469, 405, 575 |
| 5 | 241, 70, 469, 135, 575 |
| 7 | 241, 14, 469, 27, 115 |
| 241, 2, 67, 27, 115 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 241 x 2 x 67 x 27 x 115 = 21057302700
Therefore, the lowest common multiple of 723,420,469,810,575 is 21057302700.
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.
723 x 420 x 469 x 810 x 575 = 66330503505000
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.
723 : 1, 3, 241, 723
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
469 : 1, 7, 67, 469
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
575 : 1, 5, 23, 25, 115, 575
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,420,469,810,575, is 1.
Now, the common factors can be found like this.
723:3x 241
420:2x 2x 3x 5x 7
469:7x 67
810:2x 3x 3x 3x 3x 5
575:5x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 5x 7 = 3150
Therefore, the value for common factors is 3150.
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 = 66330503505000/(1x3150)
LCM = 66330503505000/3150
LCM = 21057302700
Thus, we can understand that the LCM of 723,420,469,810,575 is 21057302700.
