Given numbers are 442,799,807,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 442,799,807,138 is 385586214.
Find LCM of 442,799,807,138 with Prime Factorization
| 2 | 442, 799, 807, 138 |
| 3 | 221, 799, 807, 69 |
| 17 | 221, 799, 269, 23 |
| 13, 47, 269, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 13 x 47 x 269 x 23 = 385586214
Therefore, the lowest common multiple of 442,799,807,138 is 385586214.
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.
442 x 799 x 807 x 138 = 39329793828
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.
442 : 1, 2, 13, 17, 26, 34, 221, 442
799 : 1, 17, 47, 799
807 : 1, 3, 269, 807
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,799,807,138, is 1.
Now, the common factors can be found like this.
442:2x 13x 17
799:17x 47
807:3x 269
138:2x 3x 23
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 17 = 102
Therefore, the value for common factors is 102.
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 = 39329793828/(1x102)
LCM = 39329793828/102
LCM = 385586214
Thus, we can understand that the LCM of 442,799,807,138 is 385586214.
