Given numbers are 469,490,451,126,861
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 469,490,451,126,861 is 133256970.
Find LCM of 469,490,451,126,861 with Prime Factorization
| 2 | 469, 490, 451, 126, 861 |
| 3 | 469, 245, 451, 63, 861 |
| 7 | 469, 245, 451, 21, 287 |
| 41 | 67, 35, 451, 3, 41 |
| 67, 35, 11, 3, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 41 x 67 x 35 x 11 x 3 x 1 = 133256970
Therefore, the lowest common multiple of 469,490,451,126,861 is 133256970.
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.
469 x 490 x 451 x 126 x 861 = 11243956614660
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.
469 : 1, 7, 67, 469
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
451 : 1, 11, 41, 451
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 469,490,451,126,861, is 1.
Now, the common factors can be found like this.
469:7x 67
490:2x 5x 7x 7
451:11x 41
126:2x 3x 3x 7
861:3x 7x 41
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 7x 7x 7x 41 = 84378
Therefore, the value for common factors is 84378.
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 = 11243956614660/(1x84378)
LCM = 11243956614660/84378
LCM = 133256970
Thus, we can understand that the LCM of 469,490,451,126,861 is 133256970.
