Given numbers are 289,869,884,715
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 289,869,884,715 is 65296660.
Find LCM of 289,869,884,715 with Prime Factorization
11 | 289, 869, 884, 715 |
13 | 289, 79, 884, 65 |
17 | 289, 79, 68, 5 |
17, 79, 4, 5 |
Multiply the prime numbers at the bottom and the left side.
11 x 13 x 17 x 17 x 79 x 4 x 5 = 65296660
Therefore, the lowest common multiple of 289,869,884,715 is 65296660.
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.
289 x 869 x 884 x 715 = 158736180460
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.
289 : 1, 17, 289
869 : 1, 11, 79, 869
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
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 289,869,884,715, is 1.
Now, the common factors can be found like this.
289:17x 17
869:11x 79
884:2x 2x 13x 17
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 13x 17 = 2431
Therefore, the value for common factors is 2431.
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 = 158736180460/(1x2431)
LCM = 158736180460/2431
LCM = 65296660
Thus, we can understand that the LCM of 289,869,884,715 is 65296660.
