Given numbers are 169,788,286,338
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 169,788,286,338 is 1464892.
Find LCM of 169,788,286,338 with Prime Factorization
| 2 | 169, 788, 286, 338 |
| 13 | 169, 394, 143, 169 |
| 13 | 13, 394, 11, 13 |
| 1, 394, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 13 x 1 x 394 x 11 x 1 = 1464892
Therefore, the lowest common multiple of 169,788,286,338 is 1464892.
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.
169 x 788 x 286 x 338 = 12873470896
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.
169 : 1, 13, 169
788 : 1, 2, 4, 197, 394, 788
286 : 1, 2, 11, 13, 22, 26, 143, 286
338 : 1, 2, 13, 26, 169, 338
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,788,286,338, is 1.
Now, the common factors can be found like this.
169:13x 13
788:2x 2x 197
286:2x 11x 13
338:2x 13x 13
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 13x 13x 13 = 8788
Therefore, the value for common factors is 8788.
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 = 12873470896/(1x8788)
LCM = 12873470896/8788
LCM = 1464892
Thus, we can understand that the LCM of 169,788,286,338 is 1464892.
