Given numbers are 429,442,558,791,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 429,442,558,791,921 is 329407904826.
Find LCM of 429,442,558,791,921 with Prime Factorization
| 2 | 429, 442, 558, 791, 921 |
| 3 | 429, 221, 279, 791, 921 |
| 13 | 143, 221, 93, 791, 307 |
| 11, 17, 93, 791, 307 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 11 x 17 x 93 x 791 x 307 = 329407904826
Therefore, the lowest common multiple of 429,442,558,791,921 is 329407904826.
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 442 x 558 x 791 x 921 = 77081449729284
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
442 : 1, 2, 13, 17, 26, 34, 221, 442
558 : 1, 2, 3, 6, 9, 18, 31, 62, 93, 186, 279, 558
791 : 1, 7, 113, 791
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 429,442,558,791,921, is 1.
Now, the common factors can be found like this.
429:3x 11x 13
442:2x 13x 17
558:2x 3x 3x 31
791:7x 113
921:3x 307
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 13 = 234
Therefore, the value for common factors is 234.
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 = 77081449729284/(1x234)
LCM = 77081449729284/234
LCM = 329407904826
Thus, we can understand that the LCM of 429,442,558,791,921 is 329407904826.
