Find LCM of 816,155,478,740,160 with Prime Factorization
| 2 | 816, 155, 478, 740, 160 |
| 2 | 408, 155, 239, 370, 80 |
| 2 | 204, 155, 239, 185, 40 |
| 2 | 102, 155, 239, 185, 20 |
| 5 | 51, 155, 239, 185, 10 |
| 51, 31, 239, 37, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 5 x 51 x 31 x 239 x 37 x 2 = 2236925280
Therefore, the lowest common multiple of 816,155,478,740,160 is 2236925280.
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.
816 x 155 x 478 x 740 x 160 = 7158160896000
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.
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
155 : 1, 5, 31, 155
478 : 1, 2, 239, 478
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
160 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 80, 160
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,155,478,740,160, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
155:5x 31
478:2x 239
740:2x 2x 5x 37
160:2x 2x 2x 2x 2x 5
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 5x 5 = 3200
Therefore, the value for common factors is 3200.
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 = 7158160896000/(1x3200)
LCM = 7158160896000/3200
LCM = 2236925280
Thus, we can understand that the LCM of 816,155,478,740,160 is 2236925280.
