Given numbers are 399,732,740,671
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 399,732,740,671 is 198119460.
Find LCM of 399,732,740,671 with Prime Factorization
| 2 | 399, 732, 740, 671 |
| 2 | 399, 366, 370, 671 |
| 3 | 399, 183, 185, 671 |
| 61 | 133, 61, 185, 671 |
| 133, 1, 185, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 61 x 133 x 1 x 185 x 11 = 198119460
Therefore, the lowest common multiple of 399,732,740,671 is 198119460.
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.
399 x 732 x 740 x 671 = 145023444720
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.
399 : 1, 3, 7, 19, 21, 57, 133, 399
732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732
740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740
671 : 1, 11, 61, 671
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 399,732,740,671, is 1.
Now, the common factors can be found like this.
399:3x 7x 19
732:2x 2x 3x 61
740:2x 2x 5x 37
671:11x 61
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 61 = 732
Therefore, the value for common factors is 732.
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 = 145023444720/(1x732)
LCM = 145023444720/732
LCM = 198119460
Thus, we can understand that the LCM of 399,732,740,671 is 198119460.
