Given numbers are 374,561,287,715
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 374,561,287,715 is 20930910.
Find LCM of 374,561,287,715 with Prime Factorization
| 11 | 374, 561, 287, 715 |
| 17 | 34, 51, 287, 65 |
| 2, 3, 287, 65 |
Multiply the prime numbers at the bottom and the left side.
11 x 17 x 2 x 3 x 287 x 65 = 20930910
Therefore, the lowest common multiple of 374,561,287,715 is 20930910.
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.
374 x 561 x 287 x 715 = 43054881870
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.
374 : 1, 2, 11, 17, 22, 34, 187, 374
561 : 1, 3, 11, 17, 33, 51, 187, 561
287 : 1, 7, 41, 287
715 : 1, 5, 11, 13, 55, 65, 143, 715
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 374,561,287,715, is 1.
Now, the common factors can be found like this.
374:2x 11x 17
561:3x 11x 17
287:7x 41
715:5x 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.
11x 11x 17 = 2057
Therefore, the value for common factors is 2057.
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 = 43054881870/(1x2057)
LCM = 43054881870/2057
LCM = 20930910
Thus, we can understand that the LCM of 374,561,287,715 is 20930910.
