Given numbers are 192,397,540,946
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 192,397,540,946 is 1622427840.
Find LCM of 192,397,540,946 with Prime Factorization
| 2 | 192, 397, 540, 946 |
| 2 | 96, 397, 270, 473 |
| 3 | 48, 397, 135, 473 |
| 16, 397, 45, 473 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 16 x 397 x 45 x 473 = 1622427840
Therefore, the lowest common multiple of 192,397,540,946 is 1622427840.
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.
192 x 397 x 540 x 946 = 38938268160
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.
192 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 192
397 : 1, 397
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
946 : 1, 2, 11, 22, 43, 86, 473, 946
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 192,397,540,946, is 1.
Now, the common factors can be found like this.
192:2x 2x 2x 2x 2x 2x 3
397:397
540:2x 2x 3x 3x 3x 5
946:2x 11x 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 2x 3 = 24
Therefore, the value for common factors is 24.
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 = 38938268160/(1x24)
LCM = 38938268160/24
LCM = 1622427840
Thus, we can understand that the LCM of 192,397,540,946 is 1622427840.
