Find LCM of 258,443,485,140,540 with Prime Factorization
| 2 | 258, 443, 485, 140, 540 |
| 2 | 129, 443, 485, 70, 270 |
| 3 | 129, 443, 485, 35, 135 |
| 5 | 43, 443, 485, 35, 45 |
| 43, 443, 97, 7, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 43 x 443 x 97 x 7 x 9 = 6984506340
Therefore, the lowest common multiple of 258,443,485,140,540 is 6984506340.
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.
258 x 443 x 485 x 140 x 540 = 4190703804000
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.
258 : 1, 2, 3, 6, 43, 86, 129, 258
443 : 1, 443
485 : 1, 5, 97, 485
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 258,443,485,140,540, is 1.
Now, the common factors can be found like this.
258:2x 3x 43
443:443
485:5x 97
140:2x 2x 5x 7
540:2x 2x 3x 3x 3x 5
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 5x 5 = 600
Therefore, the value for common factors is 600.
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 = 4190703804000/(1x600)
LCM = 4190703804000/600
LCM = 6984506340
Thus, we can understand that the LCM of 258,443,485,140,540 is 6984506340.
