Given numbers are 258,946,536,645
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 258,946,536,645 is 3802920.
Find LCM of 258,946,536,645 with Prime Factorization
| 2 | 258, 946, 536, 645 |
| 3 | 129, 473, 268, 645 |
| 43 | 43, 473, 268, 215 |
| 1, 11, 268, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 43 x 1 x 11 x 268 x 5 = 3802920
Therefore, the lowest common multiple of 258,946,536,645 is 3802920.
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.
258 x 946 x 536 x 645 = 84379188960
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.
258 : 1, 2, 3, 6, 43, 86, 129, 258
946 : 1, 2, 11, 22, 43, 86, 473, 946
536 : 1, 2, 4, 8, 67, 134, 268, 536
645 : 1, 3, 5, 15, 43, 129, 215, 645
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 258,946,536,645, is 1.
Now, the common factors can be found like this.
258:2x 3x 43
946:2x 11x 43
536:2x 2x 2x 67
645:3x 5x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 43x 43 = 22188
Therefore, the value for common factors is 22188.
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 = 84379188960/(1x22188)
LCM = 84379188960/22188
LCM = 3802920
Thus, we can understand that the LCM of 258,946,536,645 is 3802920.
