Find LCM of 467,405,842,756,921 with Prime Factorization
| 2 | 467, 405, 842, 756, 921 |
| 3 | 467, 405, 421, 378, 921 |
| 3 | 467, 135, 421, 126, 307 |
| 3 | 467, 45, 421, 42, 307 |
| 467, 15, 421, 14, 307 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 467 x 15 x 421 x 14 x 307 = 684463677660
Therefore, the lowest common multiple of 467,405,842,756,921 is 684463677660.
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.
467 x 405 x 842 x 756 x 921 = 110883115780920
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.
467 : 1, 467
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
842 : 1, 2, 421, 842
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 467,405,842,756,921, is 1.
Now, the common factors can be found like this.
467:467
405:3x 3x 3x 3x 5
842:2x 421
756:2x 2x 3x 3x 3x 7
921:3x 307
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 3x 3 = 162
Therefore, the value for common factors is 162.
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 = 110883115780920/(1x162)
LCM = 110883115780920/162
LCM = 684463677660
Thus, we can understand that the LCM of 467,405,842,756,921 is 684463677660.
