Find LCM of 811,208,390,138,301 with Prime Factorization
| 2 | 811, 208, 390, 138, 301 |
| 3 | 811, 104, 195, 69, 301 |
| 13 | 811, 104, 65, 23, 301 |
| 811, 8, 5, 23, 301 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 811 x 8 x 5 x 23 x 301 = 17517405360
Therefore, the lowest common multiple of 811,208,390,138,301 is 17517405360.
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.
811 x 208 x 390 x 138 x 301 = 2732715236160
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.
811 : 1, 811
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
138 : 1, 2, 3, 6, 23, 46, 69, 138
301 : 1, 7, 43, 301
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 811,208,390,138,301, is 1.
Now, the common factors can be found like this.
811:811
208:2x 2x 2x 2x 13
390:2x 3x 5x 13
138:2x 3x 23
301:7x 43
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 3x 13 = 156
Therefore, the value for common factors is 156.
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 = 2732715236160/(1x156)
LCM = 2732715236160/156
LCM = 17517405360
Thus, we can understand that the LCM of 811,208,390,138,301 is 17517405360.
