Find LCM of 455,988,361,290,811 with Prime Factorization
| 2 | 455, 988, 361, 290, 811 |
| 5 | 455, 494, 361, 145, 811 |
| 13 | 91, 494, 361, 29, 811 |
| 19 | 7, 38, 361, 29, 811 |
| 7, 2, 19, 29, 811 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 19 x 7 x 2 x 19 x 29 x 811 = 15452453380
Therefore, the lowest common multiple of 455,988,361,290,811 is 15452453380.
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.
455 x 988 x 361 x 290 x 811 = 38167559848600
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.
455 : 1, 5, 7, 13, 35, 65, 91, 455
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
361 : 1, 19, 361
290 : 1, 2, 5, 10, 29, 58, 145, 290
811 : 1, 811
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 455,988,361,290,811, is 1.
Now, the common factors can be found like this.
455:5x 7x 13
988:2x 2x 13x 19
361:19x 19
290:2x 5x 29
811:811
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13x 19 = 2470
Therefore, the value for common factors is 2470.
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 = 38167559848600/(1x2470)
LCM = 38167559848600/2470
LCM = 15452453380
Thus, we can understand that the LCM of 455,988,361,290,811 is 15452453380.
