Find LCM of 501,576,784,648 with Prime Factorization
| 2 | 501, 576, 784, 648 |
| 2 | 501, 288, 392, 324 |
| 2 | 501, 144, 196, 162 |
| 2 | 501, 72, 98, 81 |
| 3 | 501, 36, 49, 81 |
| 3 | 167, 12, 49, 27 |
| 167, 4, 49, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 3 x 167 x 4 x 49 x 9 = 42420672
Therefore, the lowest common multiple of 501,576,784,648 is 42420672.
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.
501 x 576 x 784 x 648 = 146605842432
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.
501 : 1, 3, 167, 501
576 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 64, 72, 96, 144, 192, 288, 576
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 501,576,784,648, is 1.
Now, the common factors can be found like this.
501:3x 167
576:2x 2x 2x 2x 2x 2x 3x 3
784:2x 2x 2x 2x 7x 7
648:2x 2x 2x 3x 3x 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 3x 3x 3 = 3456
Therefore, the value for common factors is 3456.
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 = 146605842432/(1x3456)
LCM = 146605842432/3456
LCM = 42420672
Thus, we can understand that the LCM of 501,576,784,648 is 42420672.
