Given numbers are 728,845,741,919
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 728,845,741,919 is 2478763560.
Find LCM of 728,845,741,919 with Prime Factorization
13 | 728, 845, 741, 919 |
56, 65, 57, 919 |
Multiply the prime numbers at the bottom and the left side.
13 x 56 x 65 x 57 x 919 = 2478763560
Therefore, the lowest common multiple of 728,845,741,919 is 2478763560.
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.
728 x 845 x 741 x 919 = 418911041640
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.
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
845 : 1, 5, 13, 65, 169, 845
741 : 1, 3, 13, 19, 39, 57, 247, 741
919 : 1, 919
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 728,845,741,919, is 1.
Now, the common factors can be found like this.
728:2x 2x 2x 7x 13
845:5x 13x 13
741:3x 13x 19
919:919
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 13 = 169
Therefore, the value for common factors is 169.
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 = 418911041640/(1x169)
LCM = 418911041640/169
LCM = 2478763560
Thus, we can understand that the LCM of 728,845,741,919 is 2478763560.
