Given numbers are 723,181,247,168,429
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 723,181,247,168,429 is 19911067176.
Find LCM of 723,181,247,168,429 with Prime Factorization
| 3 | 723, 181, 247, 168, 429 |
| 13 | 241, 181, 247, 56, 143 |
| 241, 181, 19, 56, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 241 x 181 x 19 x 56 x 11 = 19911067176
Therefore, the lowest common multiple of 723,181,247,168,429 is 19911067176.
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.
723 x 181 x 247 x 168 x 429 = 2329594859592
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.
723 : 1, 3, 241, 723
181 : 1, 181
247 : 1, 13, 19, 247
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
429 : 1, 3, 11, 13, 33, 39, 143, 429
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 723,181,247,168,429, is 1.
Now, the common factors can be found like this.
723:3x 241
181:181
247:13x 19
168:2x 2x 2x 3x 7
429:3x 11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13 = 117
Therefore, the value for common factors is 117.
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 = 2329594859592/(1x117)
LCM = 2329594859592/117
LCM = 19911067176
Thus, we can understand that the LCM of 723,181,247,168,429 is 19911067176.
