Find LCM of 856,640,405,198,149 with Prime Factorization
| 2 | 856, 640, 405, 198, 149 |
| 2 | 428, 320, 405, 99, 149 |
| 2 | 214, 160, 405, 99, 149 |
| 3 | 107, 80, 405, 99, 149 |
| 3 | 107, 80, 135, 33, 149 |
| 5 | 107, 80, 45, 11, 149 |
| 107, 16, 9, 11, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 5 x 107 x 16 x 9 x 11 x 149 = 9091336320
Therefore, the lowest common multiple of 856,640,405,198,149 is 9091336320.
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.
856 x 640 x 405 x 198 x 149 = 6545762150400
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.
856 : 1, 2, 4, 8, 107, 214, 428, 856
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
149 : 1, 149
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,640,405,198,149, is 1.
Now, the common factors can be found like this.
856:2x 2x 2x 107
640:2x 2x 2x 2x 2x 2x 2x 5
405:3x 3x 3x 3x 5
198:2x 3x 3x 11
149:149
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 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 6545762150400/(1x720)
LCM = 6545762150400/720
LCM = 9091336320
Thus, we can understand that the LCM of 856,640,405,198,149 is 9091336320.
