The LCM of 685,256,344,784,132 is 12192956160.
Find LCM of 685,256,344,784,132 with Prime Factorization
| 2 | 685, 256, 344, 784, 132 |
| 2 | 685, 128, 172, 392, 66 |
| 2 | 685, 64, 86, 196, 33 |
| 2 | 685, 32, 43, 98, 33 |
| 685, 16, 43, 49, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 685 x 16 x 43 x 49 x 33 = 12192956160
Therefore, the lowest common multiple of 685,256,344,784,132 is 12192956160.
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.
685 x 256 x 344 x 784 x 132 = 6242793553920
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.
685 : 1, 5, 137, 685
256 : 1, 2, 4, 8, 16, 32, 64, 128, 256
344 : 1, 2, 4, 8, 43, 86, 172, 344
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,256,344,784,132, is 1.
Now, the common factors can be found like this.
685:5x 137
256:2x 2x 2x 2x 2x 2x 2x 2
344:2x 2x 2x 43
784:2x 2x 2x 2x 7x 7
132:2x 2x 3x 11
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 2 = 512
Therefore, the value for common factors is 512.
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 = 6242793553920/(1x512)
LCM = 6242793553920/512
LCM = 12192956160
Thus, we can understand that the LCM of 685,256,344,784,132 is 12192956160.
