Find LCM of 858,720,736,576 with Prime Factorization
| 2 | 858, 720, 736, 576 |
| 2 | 429, 360, 368, 288 |
| 2 | 429, 180, 184, 144 |
| 2 | 429, 90, 92, 72 |
| 2 | 429, 45, 46, 36 |
| 3 | 429, 45, 23, 18 |
| 3 | 143, 15, 23, 6 |
| 143, 5, 23, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 3 x 143 x 5 x 23 x 2 = 9472320
Therefore, the lowest common multiple of 858,720,736,576 is 9472320.
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.
858 x 720 x 736 x 576 = 261890703360
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.
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 858,720,736,576, is 2.
Now, the common factors can be found like this.
858:2x 3x 11x 13
720:2x 2x 2x 2x 3x 3x 5
736:2x 2x 2x 2x 2x 23
576:2x 2x 2x 2x 2x 2x 3x 3
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 2x 2x 2x 3x 3x 3 = 13824
Therefore, the value for common factors is 13824.
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 = 261890703360/(2x13824)
LCM = 261890703360/27648
LCM = 9472320
Thus, we can understand that the LCM of 858,720,736,576 is 9472320.
