Given numbers are 321,786,874,450,342
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 321,786,874,450,342 is 2756443050.
Find LCM of 321,786,874,450,342 with Prime Factorization
| 2 | 321, 786, 874, 450, 342 |
| 3 | 321, 393, 437, 225, 171 |
| 3 | 107, 131, 437, 75, 57 |
| 19 | 107, 131, 437, 25, 19 |
| 107, 131, 23, 25, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 19 x 107 x 131 x 23 x 25 x 1 = 2756443050
Therefore, the lowest common multiple of 321,786,874,450,342 is 2756443050.
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.
321 x 786 x 874 x 450 x 342 = 33937326831600
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.
321 : 1, 3, 107, 321
786 : 1, 2, 3, 6, 131, 262, 393, 786
874 : 1, 2, 19, 23, 38, 46, 437, 874
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 321,786,874,450,342, is 1.
Now, the common factors can be found like this.
321:3x 107
786:2x 3x 131
874:2x 19x 23
450:2x 3x 3x 5x 5
342:2x 3x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 3x 3x 3x 3x 19 = 12312
Therefore, the value for common factors is 12312.
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 = 33937326831600/(1x12312)
LCM = 33937326831600/12312
LCM = 2756443050
Thus, we can understand that the LCM of 321,786,874,450,342 is 2756443050.
