Find LCM of 311,161,803,876,315 with Prime Factorization
| 3 | 311, 161, 803, 876, 315 |
| 7 | 311, 161, 803, 292, 105 |
| 73 | 311, 23, 803, 292, 15 |
| 311, 23, 11, 4, 15 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 73 x 311 x 23 x 11 x 4 x 15 = 7237262340
Therefore, the lowest common multiple of 311,161,803,876,315 is 7237262340.
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.
311 x 161 x 803 x 876 x 315 = 11094723167220
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.
311 : 1, 311
161 : 1, 7, 23, 161
803 : 1, 11, 73, 803
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 311,161,803,876,315, is 1.
Now, the common factors can be found like this.
311:311
161:7x 23
803:11x 73
876:2x 2x 3x 73
315:3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 73 = 1533
Therefore, the value for common factors is 1533.
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 = 11094723167220/(1x1533)
LCM = 11094723167220/1533
LCM = 7237262340
Thus, we can understand that the LCM of 311,161,803,876,315 is 7237262340.
