Given numbers are 409,943,391,574
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 409,943,391,574 is 91793506.
Find LCM of 409,943,391,574 with Prime Factorization
| 23 | 409, 943, 391, 574 |
| 41 | 409, 41, 17, 574 |
| 409, 1, 17, 14 |
Multiply the prime numbers at the bottom and the left side.
23 x 41 x 409 x 1 x 17 x 14 = 91793506
Therefore, the lowest common multiple of 409,943,391,574 is 91793506.
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.
409 x 943 x 391 x 574 = 86561276158
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.
409 : 1, 409
943 : 1, 23, 41, 943
391 : 1, 17, 23, 391
574 : 1, 2, 7, 14, 41, 82, 287, 574
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,943,391,574, is 1.
Now, the common factors can be found like this.
409:409
943:23x 41
391:17x 23
574:2x 7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 41 = 943
Therefore, the value for common factors is 943.
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 = 86561276158/(1x943)
LCM = 86561276158/943
LCM = 91793506
Thus, we can understand that the LCM of 409,943,391,574 is 91793506.
