Find LCM of 421,704,614,286,440 with Prime Factorization
| 2 | 421, 704, 614, 286, 440 |
| 2 | 421, 352, 307, 143, 220 |
| 2 | 421, 176, 307, 143, 110 |
| 11 | 421, 88, 307, 143, 55 |
| 421, 8, 307, 13, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 11 x 421 x 8 x 307 x 13 x 5 = 5914342720
Therefore, the lowest common multiple of 421,704,614,286,440 is 5914342720.
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.
421 x 704 x 614 x 286 x 440 = 22900335011840
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.
421 : 1, 421
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
614 : 1, 2, 307, 614
286 : 1, 2, 11, 13, 22, 26, 143, 286
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,704,614,286,440, is 1.
Now, the common factors can be found like this.
421:421
704:2x 2x 2x 2x 2x 2x 11
614:2x 307
286:2x 11x 13
440:2x 2x 2x 5x 11
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 2x 11x 11 = 3872
Therefore, the value for common factors is 3872.
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 = 22900335011840/(1x3872)
LCM = 22900335011840/3872
LCM = 5914342720
Thus, we can understand that the LCM of 421,704,614,286,440 is 5914342720.
