Given numbers are 431,667,812,923
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 431,667,812,923 is 7429555588.
Find LCM of 431,667,812,923 with Prime Factorization
| 29 | 431, 667, 812, 923 |
| 431, 23, 28, 923 |
Multiply the prime numbers at the bottom and the left side.
29 x 431 x 23 x 28 x 923 = 7429555588
Therefore, the lowest common multiple of 431,667,812,923 is 7429555588.
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.
431 x 667 x 812 x 923 = 215457112052
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.
431 : 1, 431
667 : 1, 23, 29, 667
812 : 1, 2, 4, 7, 14, 28, 29, 58, 116, 203, 406, 812
923 : 1, 13, 71, 923
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,667,812,923, is 1.
Now, the common factors can be found like this.
431:431
667:23x 29
812:2x 2x 7x 29
923:13x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
29 = 29
Therefore, the value for common factors is 29.
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 = 215457112052/(1x29)
LCM = 215457112052/29
LCM = 7429555588
Thus, we can understand that the LCM of 431,667,812,923 is 7429555588.
