Given numbers are 403,442,728,891
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,442,728,891 is 341837496.
Find LCM of 403,442,728,891 with Prime Factorization
2 | 403, 442, 728, 891 |
13 | 403, 221, 364, 891 |
31, 17, 28, 891 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 31 x 17 x 28 x 891 = 341837496
Therefore, the lowest common multiple of 403,442,728,891 is 341837496.
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.
403 x 442 x 728 x 891 = 115541073648
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.
403 : 1, 13, 31, 403
442 : 1, 2, 13, 17, 26, 34, 221, 442
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
891 : 1, 3, 9, 11, 27, 33, 81, 99, 297, 891
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,442,728,891, is 1.
Now, the common factors can be found like this.
403:13x 31
442:2x 13x 17
728:2x 2x 2x 7x 13
891:3x 3x 3x 3x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 13 = 338
Therefore, the value for common factors is 338.
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 = 115541073648/(1x338)
LCM = 115541073648/338
LCM = 341837496
Thus, we can understand that the LCM of 403,442,728,891 is 341837496.
