Find LCM of 810,245,762,826 with Prime Factorization
| 2 | 810, 245, 762, 826 |
| 3 | 405, 245, 381, 413 |
| 5 | 135, 245, 127, 413 |
| 7 | 27, 49, 127, 413 |
| 27, 7, 127, 59 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 27 x 7 x 127 x 59 = 297397170
Therefore, the lowest common multiple of 810,245,762,826 is 297397170.
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.
810 x 245 x 762 x 826 = 124906811400
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.
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
245 : 1, 5, 7, 35, 49, 245
762 : 1, 2, 3, 6, 127, 254, 381, 762
826 : 1, 2, 7, 14, 59, 118, 413, 826
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 810,245,762,826, is 1.
Now, the common factors can be found like this.
810:2x 3x 3x 3x 3x 5
245:5x 7x 7
762:2x 3x 127
826:2x 7x 59
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 3x 5x 7 = 420
Therefore, the value for common factors is 420.
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 = 124906811400/(1x420)
LCM = 124906811400/420
LCM = 297397170
Thus, we can understand that the LCM of 810,245,762,826 is 297397170.
