The LCM of 169,338,969,855 is 4912830.
Find LCM of 169,338,969,855 with Prime Factorization
| 3 | 169, 338, 969, 855 |
| 13 | 169, 338, 323, 285 |
| 13 | 13, 26, 323, 285 |
| 19 | 1, 2, 323, 285 |
| 1, 2, 17, 15 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 13 x 19 x 1 x 2 x 17 x 15 = 4912830
Therefore, the lowest common multiple of 169,338,969,855 is 4912830.
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 338 x 969 x 855 = 47325291390
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
338 : 1, 2, 13, 26, 169, 338
969 : 1, 3, 17, 19, 51, 57, 323, 969
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,338,969,855, is 1.
Now, the common factors can be found like this.
169:13x 13
338:2x 13x 13
969:3x 17x 19
855:3x 3x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 13x 19 = 9633
Therefore, the value for common factors is 9633.
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 = 47325291390/(1x9633)
LCM = 47325291390/9633
LCM = 4912830
Thus, we can understand that the LCM of 169,338,969,855 is 4912830.
