Given numbers are 351,988,949,921
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 351,988,949,921 is 597835836.
Find LCM of 351,988,949,921 with Prime Factorization
| 3 | 351, 988, 949, 921 |
| 13 | 117, 988, 949, 307 |
| 9, 76, 73, 307 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 9 x 76 x 73 x 307 = 597835836
Therefore, the lowest common multiple of 351,988,949,921 is 597835836.
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.
351 x 988 x 949 x 921 = 303102768852
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.
351 : 1, 3, 9, 13, 27, 39, 117, 351
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
949 : 1, 13, 73, 949
921 : 1, 3, 307, 921
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 351,988,949,921, is 1.
Now, the common factors can be found like this.
351:3x 3x 3x 13
988:2x 2x 13x 19
949:13x 73
921:3x 307
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 13 = 507
Therefore, the value for common factors is 507.
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 = 303102768852/(1x507)
LCM = 303102768852/507
LCM = 597835836
Thus, we can understand that the LCM of 351,988,949,921 is 597835836.
