Find LCM of 168,361,309,216,621 with Prime Factorization
| 2 | 168, 361, 309, 216, 621 |
| 2 | 84, 361, 309, 108, 621 |
| 2 | 42, 361, 309, 54, 621 |
| 3 | 21, 361, 309, 27, 621 |
| 3 | 7, 361, 103, 9, 207 |
| 3 | 7, 361, 103, 3, 69 |
| 7, 361, 103, 1, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 3 x 7 x 361 x 103 x 1 x 23 = 1293076008
Therefore, the lowest common multiple of 168,361,309,216,621 is 1293076008.
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.
168 x 361 x 309 x 216 x 621 = 2513739759552
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.
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
361 : 1, 19, 361
309 : 1, 3, 103, 309
216 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 108, 216
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,361,309,216,621, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
361:19x 19
309:3x 103
216:2x 2x 2x 3x 3x 3
621:3x 3x 3x 23
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 3x 3x 3x 3 = 1944
Therefore, the value for common factors is 1944.
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 = 2513739759552/(1x1944)
LCM = 2513739759552/1944
LCM = 1293076008
Thus, we can understand that the LCM of 168,361,309,216,621 is 1293076008.
