Given numbers are 403,585,976,915
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,585,976,915 is 17699760.
Find LCM of 403,585,976,915 with Prime Factorization
3 | 403, 585, 976, 915 |
5 | 403, 195, 976, 305 |
13 | 403, 39, 976, 61 |
61 | 31, 3, 976, 61 |
31, 3, 16, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 13 x 61 x 31 x 3 x 16 x 1 = 17699760
Therefore, the lowest common multiple of 403,585,976,915 is 17699760.
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 585 x 976 x 915 = 210538645200
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
585 : 1, 3, 5, 9, 13, 15, 39, 45, 65, 117, 195, 585
976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976
915 : 1, 3, 5, 15, 61, 183, 305, 915
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,585,976,915, is 1.
Now, the common factors can be found like this.
403:13x 31
585:3x 3x 5x 13
976:2x 2x 2x 2x 61
915:3x 5x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 13x 61 = 11895
Therefore, the value for common factors is 11895.
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 = 210538645200/(1x11895)
LCM = 210538645200/11895
LCM = 17699760
Thus, we can understand that the LCM of 403,585,976,915 is 17699760.
