Find LCM of 816,785,584,135 with Prime Factorization
| 2 | 816, 785, 584, 135 |
| 2 | 408, 785, 292, 135 |
| 2 | 204, 785, 146, 135 |
| 3 | 102, 785, 73, 135 |
| 5 | 34, 785, 73, 45 |
| 34, 157, 73, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 34 x 157 x 73 x 9 = 420847920
Therefore, the lowest common multiple of 816,785,584,135 is 420847920.
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 785 x 584 x 135 = 50501750400
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
785 : 1, 5, 157, 785
584 : 1, 2, 4, 8, 73, 146, 292, 584
135 : 1, 3, 5, 9, 15, 27, 45, 135
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,785,584,135, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
785:5x 157
584:2x 2x 2x 73
135:3x 3x 3x 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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 50501750400/(1x120)
LCM = 50501750400/120
LCM = 420847920
Thus, we can understand that the LCM of 816,785,584,135 is 420847920.
