Given numbers are 429,871,819
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 429,871,819 is 603603.
Find LCM of 429,871,819 with Prime Factorization
| 3 | 429, 871, 819 |
| 13 | 143, 871, 273 |
| 11, 67, 21 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 11 x 67 x 21 = 603603
Therefore, the lowest common multiple of 429,871,819 is 603603.
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.
429 x 871 x 819 = 306026721
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.
429 : 1, 3, 11, 13, 33, 39, 143, 429
871 : 1, 13, 67, 871
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
13 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 429,871,819, is 13.
Now, the common factors can be found like this.
429:3x 11x 13
871:13x 67
819:3x 3x 7x 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 13 = 39
Therefore, the value for common factors is 39.
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 = 306026721/(13x39)
LCM = 306026721/507
LCM = 603603
Thus, we can understand that the LCM of 429,871,819 is 603603.
