Find LCM of 750,729,486,396 with Prime Factorization
| 2 | 750, 729, 486, 396 |
| 3 | 375, 729, 243, 198 |
| 3 | 125, 81, 243, 66 |
| 3 | 125, 27, 81, 22 |
| 3 | 125, 9, 27, 22 |
| 3 | 125, 3, 9, 22 |
| 125, 1, 3, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 3 x 3 x 125 x 1 x 3 x 22 = 4009500
Therefore, the lowest common multiple of 750,729,486,396 is 4009500.
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.
750 x 729 x 486 x 396 = 105225318000
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.
750 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 125, 150, 250, 375, 750
729 : 1, 3, 9, 27, 81, 243, 729
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 750,729,486,396, is 3.
Now, the common factors can be found like this.
750:2x 3x 5x 5x 5
729:3x 3x 3x 3x 3x 3
486:2x 3x 3x 3x 3x 3
396:2x 2x 3x 3x 11
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 3x 3x 3x 3x 3x 3 = 8748
Therefore, the value for common factors is 8748.
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 = 105225318000/(3x8748)
LCM = 105225318000/26244
LCM = 4009500
Thus, we can understand that the LCM of 750,729,486,396 is 4009500.
