Given numbers are 921,351,559,475
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 921,351,559,475 is 2200936725.
Find LCM of 921,351,559,475 with Prime Factorization
| 3 | 921, 351, 559, 475 |
| 13 | 307, 117, 559, 475 |
| 307, 9, 43, 475 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 307 x 9 x 43 x 475 = 2200936725
Therefore, the lowest common multiple of 921,351,559,475 is 2200936725.
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.
921 x 351 x 559 x 475 = 85836532275
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.
921 : 1, 3, 307, 921
351 : 1, 3, 9, 13, 27, 39, 117, 351
559 : 1, 13, 43, 559
475 : 1, 5, 19, 25, 95, 475
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,351,559,475, is 1.
Now, the common factors can be found like this.
921:3x 307
351:3x 3x 3x 13
559:13x 43
475:5x 5x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13 = 39
Therefore, the value for common factors is 39.
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 = 85836532275/(1x39)
LCM = 85836532275/39
LCM = 2200936725
Thus, we can understand that the LCM of 921,351,559,475 is 2200936725.
