Given numbers are 442,561,173,341
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 442,561,173,341 is 78224718.
Find LCM of 442,561,173,341 with Prime Factorization
| 11 | 442, 561, 173, 341 |
| 17 | 442, 51, 173, 31 |
| 26, 3, 173, 31 |
Multiply the prime numbers at the bottom and the left side.
11 x 17 x 26 x 3 x 173 x 31 = 78224718
Therefore, the lowest common multiple of 442,561,173,341 is 78224718.
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.
442 x 561 x 173 x 341 = 14628022266
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.
442 : 1, 2, 13, 17, 26, 34, 221, 442
561 : 1, 3, 11, 17, 33, 51, 187, 561
173 : 1, 173
341 : 1, 11, 31, 341
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 442,561,173,341, is 1.
Now, the common factors can be found like this.
442:2x 13x 17
561:3x 11x 17
173:173
341:11x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 17 = 187
Therefore, the value for common factors is 187.
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 = 14628022266/(1x187)
LCM = 14628022266/187
LCM = 78224718
Thus, we can understand that the LCM of 442,561,173,341 is 78224718.
