Given numbers are 729,985,940,865,433
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 729,985,940,865,433 is 10112431843980.
Find LCM of 729,985,940,865,433 with Prime Factorization
| 5 | 729, 985, 940, 865, 433 |
| 729, 197, 188, 173, 433 |
Multiply the prime numbers at the bottom and the left side.
5 x 729 x 197 x 188 x 173 x 433 = 10112431843980
Therefore, the lowest common multiple of 729,985,940,865,433 is 10112431843980.
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.
729 x 985 x 940 x 865 x 433 = 252810796099500
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.
729 : 1, 3, 9, 27, 81, 243, 729
985 : 1, 5, 197, 985
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
865 : 1, 5, 173, 865
433 : 1, 433
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 729,985,940,865,433, is 1.
Now, the common factors can be found like this.
729:3x 3x 3x 3x 3x 3
985:5x 197
940:2x 2x 5x 47
865:5x 173
433:433
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5 = 25
Therefore, the value for common factors is 25.
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 = 252810796099500/(1x25)
LCM = 252810796099500/25
LCM = 10112431843980
Thus, we can understand that the LCM of 729,985,940,865,433 is 10112431843980.
