Given numbers are 513,396,807,42
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 513,396,807,42 is 42503076.
Find LCM of 513,396,807,42 with Prime Factorization
| 2 | 513, 396, 807, 42 |
| 3 | 513, 198, 807, 21 |
| 3 | 171, 66, 269, 7 |
| 57, 22, 269, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 57 x 22 x 269 x 7 = 42503076
Therefore, the lowest common multiple of 513,396,807,42 is 42503076.
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.
513 x 396 x 807 x 42 = 6885498312
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.
513 : 1, 3, 9, 19, 27, 57, 171, 513
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
807 : 1, 3, 269, 807
42 : 1, 2, 3, 6, 7, 14, 21, 42
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 513,396,807,42, is 3.
Now, the common factors can be found like this.
513:3x 3x 3x 19
396:2x 2x 3x 3x 11
807:3x 269
42:2x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 6885498312/(3x54)
LCM = 6885498312/162
LCM = 42503076
Thus, we can understand that the LCM of 513,396,807,42 is 42503076.
