Given numbers are 561,892,170
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,892,170 is 2502060.
Find LCM of 561,892,170 with Prime Factorization
| 2 | 561, 892, 170 |
| 17 | 561, 446, 85 |
| 33, 446, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 33 x 446 x 5 = 2502060
Therefore, the lowest common multiple of 561,892,170 is 2502060.
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 892 x 170 = 85070040
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
892 : 1, 2, 4, 223, 446, 892
170 : 1, 2, 5, 10, 17, 34, 85, 170
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,892,170, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
892:2x 2x 223
170:2x 5x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17 = 34
Therefore, the value for common factors is 34.
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 = 85070040/(1x34)
LCM = 85070040/34
LCM = 2502060
Thus, we can understand that the LCM of 561,892,170 is 2502060.
