Given numbers are 561,438,949,146
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,438,949,146 is 1064778.
Find LCM of 561,438,949,146 with Prime Factorization
| 2 | 561, 438, 949, 146 |
| 3 | 561, 219, 949, 73 |
| 73 | 187, 73, 949, 73 |
| 187, 1, 13, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 73 x 187 x 1 x 13 x 1 = 1064778
Therefore, the lowest common multiple of 561,438,949,146 is 1064778.
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.
561 x 438 x 949 x 146 = 34045211772
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
438 : 1, 2, 3, 6, 73, 146, 219, 438
949 : 1, 13, 73, 949
146 : 1, 2, 73, 146
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,438,949,146, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
438:2x 3x 73
949:13x 73
146:2x 73
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 73x 73 = 31974
Therefore, the value for common factors is 31974.
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 = 34045211772/(1x31974)
LCM = 34045211772/31974
LCM = 1064778
Thus, we can understand that the LCM of 561,438,949,146 is 1064778.
