Given numbers are 738,508,438,871
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 738,508,438,871 is 11918760516.
Find LCM of 738,508,438,871 with Prime Factorization
| 2 | 738, 508, 438, 871 |
| 3 | 369, 254, 219, 871 |
| 123, 254, 73, 871 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 123 x 254 x 73 x 871 = 11918760516
Therefore, the lowest common multiple of 738,508,438,871 is 11918760516.
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.
738 x 508 x 438 x 871 = 143025126192
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.
738 : 1, 2, 3, 6, 9, 18, 41, 82, 123, 246, 369, 738
508 : 1, 2, 4, 127, 254, 508
438 : 1, 2, 3, 6, 73, 146, 219, 438
871 : 1, 13, 67, 871
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 738,508,438,871, is 1.
Now, the common factors can be found like this.
738:2x 3x 3x 41
508:2x 2x 127
438:2x 3x 73
871:13x 67
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 3 = 12
Therefore, the value for common factors is 12.
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 = 143025126192/(1x12)
LCM = 143025126192/12
LCM = 11918760516
Thus, we can understand that the LCM of 738,508,438,871 is 11918760516.
