Find LCM of 845,325,513,765 with Prime Factorization
| 3 | 845, 325, 513, 765 |
| 3 | 845, 325, 171, 255 |
| 5 | 845, 325, 57, 85 |
| 13 | 169, 65, 57, 17 |
| 13, 5, 57, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 13 x 13 x 5 x 57 x 17 = 36846225
Therefore, the lowest common multiple of 845,325,513,765 is 36846225.
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.
845 x 325 x 513 x 765 = 107775208125
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.
845 : 1, 5, 13, 65, 169, 845
325 : 1, 5, 13, 25, 65, 325
513 : 1, 3, 9, 19, 27, 57, 171, 513
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,325,513,765, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
325:5x 5x 13
513:3x 3x 3x 19
765:3x 3x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 5x 13 = 2925
Therefore, the value for common factors is 2925.
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 = 107775208125/(1x2925)
LCM = 107775208125/2925
LCM = 36846225
Thus, we can understand that the LCM of 845,325,513,765 is 36846225.
