Find LCM of 816,842,400,179,942 with Prime Factorization
| 2 | 816, 842, 400, 179, 942 |
| 2 | 408, 421, 200, 179, 471 |
| 2 | 204, 421, 100, 179, 471 |
| 2 | 102, 421, 50, 179, 471 |
| 3 | 51, 421, 25, 179, 471 |
| 17, 421, 25, 179, 157 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 17 x 421 x 25 x 179 x 157 = 241359805200
Therefore, the lowest common multiple of 816,842,400,179,942 is 241359805200.
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 842 x 400 x 179 x 942 = 46341082598400
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
842 : 1, 2, 421, 842
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
179 : 1, 179
942 : 1, 2, 3, 6, 157, 314, 471, 942
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 816,842,400,179,942, is 1.
Now, the common factors can be found like this.
816:2x 2x 2x 2x 3x 17
842:2x 421
400:2x 2x 2x 2x 5x 5
179:179
942:2x 3x 157
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 3 = 192
Therefore, the value for common factors is 192.
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 = 46341082598400/(1x192)
LCM = 46341082598400/192
LCM = 241359805200
Thus, we can understand that the LCM of 816,842,400,179,942 is 241359805200.
