Given numbers are 921,568,451,222,918
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,568,451,222,918 is 1335603851208.
Find LCM of 921,568,451,222,918 with Prime Factorization
| 2 | 921, 568, 451, 222, 918 |
| 3 | 921, 284, 451, 111, 459 |
| 307, 284, 451, 37, 153 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 307 x 284 x 451 x 37 x 153 = 1335603851208
Therefore, the lowest common multiple of 921,568,451,222,918 is 1335603851208.
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.
921 x 568 x 451 x 222 x 918 = 48081738643488
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.
921 : 1, 3, 307, 921
568 : 1, 2, 4, 8, 71, 142, 284, 568
451 : 1, 11, 41, 451
222 : 1, 2, 3, 6, 37, 74, 111, 222
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,568,451,222,918, is 1.
Now, the common factors can be found like this.
921:3x 307
568:2x 2x 2x 71
451:11x 41
222:2x 3x 37
918:2x 3x 3x 3x 17
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 3 = 36
Therefore, the value for common factors is 36.
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 = 48081738643488/(1x36)
LCM = 48081738643488/36
LCM = 1335603851208
Thus, we can understand that the LCM of 921,568,451,222,918 is 1335603851208.
