Find LCM of 436,918,788,450,449 with Prime Factorization
| 2 | 436, 918, 788, 450, 449 |
| 2 | 218, 459, 394, 225, 449 |
| 3 | 109, 459, 197, 225, 449 |
| 3 | 109, 153, 197, 75, 449 |
| 109, 51, 197, 25, 449 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 109 x 51 x 197 x 25 x 449 = 442539204300
Therefore, the lowest common multiple of 436,918,788,450,449 is 442539204300.
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.
436 x 918 x 788 x 450 x 449 = 63725645419200
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.
436 : 1, 2, 4, 109, 218, 436
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
788 : 1, 2, 4, 197, 394, 788
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
449 : 1, 449
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 436,918,788,450,449, is 1.
Now, the common factors can be found like this.
436:2x 2x 109
918:2x 3x 3x 3x 17
788:2x 2x 197
450:2x 3x 3x 5x 5
449:449
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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 63725645419200/(1x144)
LCM = 63725645419200/144
LCM = 442539204300
Thus, we can understand that the LCM of 436,918,788,450,449 is 442539204300.
