Given numbers are 646,429,963,203
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,429,963,203 is 18058882842.
Find LCM of 646,429,963,203 with Prime Factorization
| 3 | 646, 429, 963, 203 |
| 646, 143, 321, 203 |
Multiply the prime numbers at the bottom and the left side.
3 x 646 x 143 x 321 x 203 = 18058882842
Therefore, the lowest common multiple of 646,429,963,203 is 18058882842.
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.
646 x 429 x 963 x 203 = 54176648526
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
429 : 1, 3, 11, 13, 33, 39, 143, 429
963 : 1, 3, 9, 107, 321, 963
203 : 1, 7, 29, 203
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,429,963,203, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
429:3x 11x 13
963:3x 3x 107
203:7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 54176648526/(1x3)
LCM = 54176648526/3
LCM = 18058882842
Thus, we can understand that the LCM of 646,429,963,203 is 18058882842.
