Given numbers are 747,181,913,975
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 747,181,913,975 is 483365025.
Find LCM of 747,181,913,975 with Prime Factorization
| 3 | 747, 181, 913, 975 |
| 83 | 249, 181, 913, 325 |
| 3, 181, 11, 325 |
Multiply the prime numbers at the bottom and the left side.
3 x 83 x 3 x 181 x 11 x 325 = 483365025
Therefore, the lowest common multiple of 747,181,913,975 is 483365025.
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.
747 x 181 x 913 x 975 = 120357891225
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.
747 : 1, 3, 9, 83, 249, 747
181 : 1, 181
913 : 1, 11, 83, 913
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 747,181,913,975, is 1.
Now, the common factors can be found like this.
747:3x 3x 83
181:181
913:11x 83
975:3x 5x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 83 = 249
Therefore, the value for common factors is 249.
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 = 120357891225/(1x249)
LCM = 120357891225/249
LCM = 483365025
Thus, we can understand that the LCM of 747,181,913,975 is 483365025.
