Given numbers are 353,170,442,455
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 353,170,442,455 is 5460910.
Find LCM of 353,170,442,455 with Prime Factorization
2 | 353, 170, 442, 455 |
5 | 353, 85, 221, 455 |
13 | 353, 17, 221, 91 |
17 | 353, 17, 17, 7 |
353, 1, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 17 x 353 x 1 x 1 x 7 = 5460910
Therefore, the lowest common multiple of 353,170,442,455 is 5460910.
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.
353 x 170 x 442 x 455 = 12068611100
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.
353 : 1, 353
170 : 1, 2, 5, 10, 17, 34, 85, 170
442 : 1, 2, 13, 17, 26, 34, 221, 442
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 353,170,442,455, is 1.
Now, the common factors can be found like this.
353:353
170:2x 5x 17
442:2x 13x 17
455:5x 7x 13
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 13x 17 = 2210
Therefore, the value for common factors is 2210.
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 = 12068611100/(1x2210)
LCM = 12068611100/2210
LCM = 5460910
Thus, we can understand that the LCM of 353,170,442,455 is 5460910.
