Given numbers are 561,170,317,230
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,170,317,230 is 40902510.
Find LCM of 561,170,317,230 with Prime Factorization
| 2 | 561, 170, 317, 230 |
| 5 | 561, 85, 317, 115 |
| 17 | 561, 17, 317, 23 |
| 33, 1, 317, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 33 x 1 x 317 x 23 = 40902510
Therefore, the lowest common multiple of 561,170,317,230 is 40902510.
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 170 x 317 x 230 = 6953426700
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
170 : 1, 2, 5, 10, 17, 34, 85, 170
317 : 1, 317
230 : 1, 2, 5, 10, 23, 46, 115, 230
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,170,317,230, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
170:2x 5x 17
317:317
230:2x 5x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 17 = 170
Therefore, the value for common factors is 170.
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 = 6953426700/(1x170)
LCM = 6953426700/170
LCM = 40902510
Thus, we can understand that the LCM of 561,170,317,230 is 40902510.
