Given numbers are 169,166,988,855,172
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 169,166,988,855,172 is 2062810620.
Find LCM of 169,166,988,855,172 with Prime Factorization
| 2 | 169, 166, 988, 855, 172 |
| 2 | 169, 83, 494, 855, 86 |
| 13 | 169, 83, 247, 855, 43 |
| 19 | 13, 83, 19, 855, 43 |
| 13, 83, 1, 45, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 19 x 13 x 83 x 1 x 45 x 43 = 2062810620
Therefore, the lowest common multiple of 169,166,988,855,172 is 2062810620.
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 166 x 988 x 855 x 172 = 4076113785120
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
166 : 1, 2, 83, 166
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
172 : 1, 2, 4, 43, 86, 172
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 169,166,988,855,172, is 1.
Now, the common factors can be found like this.
169:13x 13
166:2x 83
988:2x 2x 13x 19
855:3x 3x 5x 19
172:2x 2x 43
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 13x 19 = 1976
Therefore, the value for common factors is 1976.
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 = 4076113785120/(1x1976)
LCM = 4076113785120/1976
LCM = 2062810620
Thus, we can understand that the LCM of 169,166,988,855,172 is 2062810620.
