Find LCM of 418,336,280,455,359 with Prime Factorization
| 2 | 418, 336, 280, 455, 359 |
| 2 | 209, 168, 140, 455, 359 |
| 2 | 209, 84, 70, 455, 359 |
| 5 | 209, 42, 35, 455, 359 |
| 7 | 209, 42, 7, 91, 359 |
| 209, 6, 1, 13, 359 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 209 x 6 x 1 x 13 x 359 = 1638677040
Therefore, the lowest common multiple of 418,336,280,455,359 is 1638677040.
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.
418 x 336 x 280 x 455 x 359 = 6423613996800
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.
418 : 1, 2, 11, 19, 22, 38, 209, 418
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
455 : 1, 5, 7, 13, 35, 65, 91, 455
359 : 1, 359
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 418,336,280,455,359, is 1.
Now, the common factors can be found like this.
418:2x 11x 19
336:2x 2x 2x 2x 3x 7
280:2x 2x 2x 5x 7
455:5x 7x 13
359:359
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 5x 7x 7 = 3920
Therefore, the value for common factors is 3920.
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 = 6423613996800/(1x3920)
LCM = 6423613996800/3920
LCM = 1638677040
Thus, we can understand that the LCM of 418,336,280,455,359 is 1638677040.
