The LCM of 255,630,445,441 is 6672330.
Find LCM of 255,630,445,441 with Prime Factorization
| 3 | 255, 630, 445, 441 |
| 3 | 85, 210, 445, 147 |
| 5 | 85, 70, 445, 49 |
| 7 | 17, 14, 89, 49 |
| 17, 2, 89, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 17 x 2 x 89 x 7 = 6672330
Therefore, the lowest common multiple of 255,630,445,441 is 6672330.
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.
255 x 630 x 445 x 441 = 31526759250
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.
255 : 1, 3, 5, 15, 17, 51, 85, 255
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
445 : 1, 5, 89, 445
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 255,630,445,441, is 1.
Now, the common factors can be found like this.
255:3x 5x 17
630:2x 3x 3x 5x 7
445:5x 89
441:3x 3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 5x 7 = 4725
Therefore, the value for common factors is 4725.
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 = 31526759250/(1x4725)
LCM = 31526759250/4725
LCM = 6672330
Thus, we can understand that the LCM of 255,630,445,441 is 6672330.
