The LCM of 855,396,300,428 is 20126700.
Find LCM of 855,396,300,428 with Prime Factorization
| 2 | 855, 396, 300, 428 |
| 2 | 855, 198, 150, 214 |
| 3 | 855, 99, 75, 107 |
| 3 | 285, 33, 25, 107 |
| 5 | 95, 11, 25, 107 |
| 19, 11, 5, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 19 x 11 x 5 x 107 = 20126700
Therefore, the lowest common multiple of 855,396,300,428 is 20126700.
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.
855 x 396 x 300 x 428 = 43473672000
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
428 : 1, 2, 4, 107, 214, 428
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,396,300,428, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
396:2x 2x 3x 3x 11
300:2x 2x 3x 5x 5
428:2x 2x 107
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 2x 3x 3x 3x 5 = 2160
Therefore, the value for common factors is 2160.
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 = 43473672000/(1x2160)
LCM = 43473672000/2160
LCM = 20126700
Thus, we can understand that the LCM of 855,396,300,428 is 20126700.
