Given numbers are 333,561,646,391,745
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 333,561,646,391,745 is 40546516230.
Find LCM of 333,561,646,391,745 with Prime Factorization
| 3 | 333, 561, 646, 391, 745 |
| 17 | 111, 187, 646, 391, 745 |
| 111, 11, 38, 23, 745 |
Multiply the prime numbers at the bottom and the left side.
3 x 17 x 111 x 11 x 38 x 23 x 745 = 40546516230
Therefore, the lowest common multiple of 333,561,646,391,745 is 40546516230.
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.
333 x 561 x 646 x 391 x 745 = 35153829571410
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.
333 : 1, 3, 9, 37, 111, 333
561 : 1, 3, 11, 17, 33, 51, 187, 561
646 : 1, 2, 17, 19, 34, 38, 323, 646
391 : 1, 17, 23, 391
745 : 1, 5, 149, 745
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 333,561,646,391,745, is 1.
Now, the common factors can be found like this.
333:3x 3x 37
561:3x 11x 17
646:2x 17x 19
391:17x 23
745:5x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 17x 17 = 867
Therefore, the value for common factors is 867.
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 = 35153829571410/(1x867)
LCM = 35153829571410/867
LCM = 40546516230
Thus, we can understand that the LCM of 333,561,646,391,745 is 40546516230.
