Find LCM of 576,120,138,804,830 with Prime Factorization
| 2 | 576, 120, 138, 804, 830 |
| 2 | 288, 60, 69, 402, 415 |
| 2 | 144, 30, 69, 201, 415 |
| 3 | 72, 15, 69, 201, 415 |
| 5 | 24, 5, 23, 67, 415 |
| 24, 1, 23, 67, 83 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 24 x 1 x 23 x 67 x 83 = 368360640
Therefore, the lowest common multiple of 576,120,138,804,830 is 368360640.
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.
576 x 120 x 138 x 804 x 830 = 6365271859200
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.
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
138 : 1, 2, 3, 6, 23, 46, 69, 138
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
830 : 1, 2, 5, 10, 83, 166, 415, 830
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 576,120,138,804,830, is 2.
Now, the common factors can be found like this.
576:2x 2x 2x 2x 2x 2x 3x 3
120:2x 2x 2x 3x 5
138:2x 3x 23
804:2x 2x 3x 67
830:2x 5x 83
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 2x 2x 2x 2x 3x 3x 3x 5 = 8640
Therefore, the value for common factors is 8640.
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 = 6365271859200/(2x8640)
LCM = 6365271859200/17280
LCM = 368360640
Thus, we can understand that the LCM of 576,120,138,804,830 is 368360640.
