Given numbers are 423,605,957,171
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 423,605,957,171 is 141009165.
Find LCM of 423,605,957,171 with Prime Factorization
3 | 423, 605, 957, 171 |
3 | 141, 605, 319, 57 |
11 | 47, 605, 319, 19 |
47, 55, 29, 19 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 11 x 47 x 55 x 29 x 19 = 141009165
Therefore, the lowest common multiple of 423,605,957,171 is 141009165.
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.
423 x 605 x 957 x 171 = 41879722005
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.
423 : 1, 3, 9, 47, 141, 423
605 : 1, 5, 11, 55, 121, 605
957 : 1, 3, 11, 29, 33, 87, 319, 957
171 : 1, 3, 9, 19, 57, 171
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,605,957,171, is 1.
Now, the common factors can be found like this.
423:3x 3x 47
605:5x 11x 11
957:3x 11x 29
171:3x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 11 = 297
Therefore, the value for common factors is 297.
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 = 41879722005/(1x297)
LCM = 41879722005/297
LCM = 141009165
Thus, we can understand that the LCM of 423,605,957,171 is 141009165.
