Find LCM of 512,784,802,147 with Prime Factorization
| 2 | 512, 784, 802, 147 |
| 2 | 256, 392, 401, 147 |
| 2 | 128, 196, 401, 147 |
| 2 | 64, 98, 401, 147 |
| 7 | 32, 49, 401, 147 |
| 7 | 32, 7, 401, 21 |
| 32, 1, 401, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 7 x 7 x 32 x 1 x 401 x 3 = 30180864
Therefore, the lowest common multiple of 512,784,802,147 is 30180864.
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.
512 x 784 x 802 x 147 = 47323594752
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.
512 : 1, 2, 4, 8, 16, 32, 64, 128, 256, 512
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
802 : 1, 2, 401, 802
147 : 1, 3, 7, 21, 49, 147
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 512,784,802,147, is 1.
Now, the common factors can be found like this.
512:2x 2x 2x 2x 2x 2x 2x 2x 2
784:2x 2x 2x 2x 7x 7
802:2x 401
147:3x 7x 7
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 7x 7 = 1568
Therefore, the value for common factors is 1568.
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 = 47323594752/(1x1568)
LCM = 47323594752/1568
LCM = 30180864
Thus, we can understand that the LCM of 512,784,802,147 is 30180864.
