Find LCM of 572,810,715,78 with Prime Factorization
| 2 | 572, 810, 715, 78 |
| 3 | 286, 405, 715, 39 |
| 5 | 286, 135, 715, 13 |
| 11 | 286, 27, 143, 13 |
| 13 | 26, 27, 13, 13 |
| 2, 27, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 13 x 2 x 27 x 1 x 1 = 231660
Therefore, the lowest common multiple of 572,810,715,78 is 231660.
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.
572 x 810 x 715 x 78 = 25839356400
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.
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
810 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 81, 90, 135, 162, 270, 405, 810
715 : 1, 5, 11, 13, 55, 65, 143, 715
78 : 1, 2, 3, 6, 13, 26, 39, 78
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 572,810,715,78, is 1.
Now, the common factors can be found like this.
572:2x 2x 11x 13
810:2x 3x 3x 3x 3x 5
715:5x 11x 13
78:2x 3x 13
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 11x 13x 13 = 111540
Therefore, the value for common factors is 111540.
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 = 25839356400/(1x111540)
LCM = 25839356400/111540
LCM = 231660
Thus, we can understand that the LCM of 572,810,715,78 is 231660.
