Given numbers are 249,946,913,805
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 249,946,913,805 is 189620970.
Find LCM of 249,946,913,805 with Prime Factorization
| 11 | 249, 946, 913, 805 |
| 83 | 249, 86, 83, 805 |
| 3, 86, 1, 805 |
Multiply the prime numbers at the bottom and the left side.
11 x 83 x 3 x 86 x 1 x 805 = 189620970
Therefore, the lowest common multiple of 249,946,913,805 is 189620970.
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.
249 x 946 x 913 x 805 = 173123945610
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.
249 : 1, 3, 83, 249
946 : 1, 2, 11, 22, 43, 86, 473, 946
913 : 1, 11, 83, 913
805 : 1, 5, 7, 23, 35, 115, 161, 805
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,946,913,805, is 1.
Now, the common factors can be found like this.
249:3x 83
946:2x 11x 43
913:11x 83
805:5x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 83 = 913
Therefore, the value for common factors is 913.
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 = 173123945610/(1x913)
LCM = 173123945610/913
LCM = 189620970
Thus, we can understand that the LCM of 249,946,913,805 is 189620970.
