Given numbers are 355,129,923,681
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 355,129,923,681 is 135141045.
Find LCM of 355,129,923,681 with Prime Factorization
| 3 | 355, 129, 923, 681 |
| 71 | 355, 43, 923, 227 |
| 5, 43, 13, 227 |
Multiply the prime numbers at the bottom and the left side.
3 x 71 x 5 x 43 x 13 x 227 = 135141045
Therefore, the lowest common multiple of 355,129,923,681 is 135141045.
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.
355 x 129 x 923 x 681 = 28785042585
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.
355 : 1, 5, 71, 355
129 : 1, 3, 43, 129
923 : 1, 13, 71, 923
681 : 1, 3, 227, 681
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,129,923,681, is 1.
Now, the common factors can be found like this.
355:5x 71
129:3x 43
923:13x 71
681:3x 227
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 71 = 213
Therefore, the value for common factors is 213.
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 = 28785042585/(1x213)
LCM = 28785042585/213
LCM = 135141045
Thus, we can understand that the LCM of 355,129,923,681 is 135141045.
