Find LCM of 408,518,857,309,672 with Prime Factorization
| 2 | 408, 518, 857, 309, 672 |
| 2 | 204, 259, 857, 309, 336 |
| 2 | 102, 259, 857, 309, 168 |
| 3 | 51, 259, 857, 309, 84 |
| 7 | 17, 259, 857, 103, 28 |
| 17, 37, 857, 103, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 17 x 37 x 857 x 103 x 4 = 37311092448
Therefore, the lowest common multiple of 408,518,857,309,672 is 37311092448.
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.
408 x 518 x 857 x 309 x 672 = 37609581187584
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.
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
518 : 1, 2, 7, 14, 37, 74, 259, 518
857 : 1, 857
309 : 1, 3, 103, 309
672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 408,518,857,309,672, is 1.
Now, the common factors can be found like this.
408:2x 2x 2x 3x 17
518:2x 7x 37
857:857
309:3x 103
672:2x 2x 2x 2x 2x 3x 7
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 3x 7 = 1008
Therefore, the value for common factors is 1008.
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 = 37609581187584/(1x1008)
LCM = 37609581187584/1008
LCM = 37311092448
Thus, we can understand that the LCM of 408,518,857,309,672 is 37311092448.
