Given numbers are 905,663,646,429
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 905,663,646,429 is 250806270.
Find LCM of 905,663,646,429 with Prime Factorization
| 3 | 905, 663, 646, 429 |
| 13 | 905, 221, 646, 143 |
| 17 | 905, 17, 646, 11 |
| 905, 1, 38, 11 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 17 x 905 x 1 x 38 x 11 = 250806270
Therefore, the lowest common multiple of 905,663,646,429 is 250806270.
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.
905 x 663 x 646 x 429 = 166284557010
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.
905 : 1, 5, 181, 905
663 : 1, 3, 13, 17, 39, 51, 221, 663
646 : 1, 2, 17, 19, 34, 38, 323, 646
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 905,663,646,429, is 1.
Now, the common factors can be found like this.
905:5x 181
663:3x 13x 17
646:2x 17x 19
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 13x 17 = 663
Therefore, the value for common factors is 663.
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 = 166284557010/(1x663)
LCM = 166284557010/663
LCM = 250806270
Thus, we can understand that the LCM of 905,663,646,429 is 250806270.
