Find LCM of 551,440,361,312,270 with Prime Factorization
| 2 | 551, 440, 361, 312, 270 |
| 2 | 551, 220, 361, 156, 135 |
| 2 | 551, 110, 361, 78, 135 |
| 3 | 551, 55, 361, 39, 135 |
| 5 | 551, 55, 361, 13, 45 |
| 19 | 551, 11, 361, 13, 9 |
| 29, 11, 19, 13, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 19 x 29 x 11 x 19 x 13 x 9 = 1616832360
Therefore, the lowest common multiple of 551,440,361,312,270 is 1616832360.
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.
551 x 440 x 361 x 312 x 270 = 7372755561600
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.
551 : 1, 19, 29, 551
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
361 : 1, 19, 361
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
270 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,440,361,312,270, is 1.
Now, the common factors can be found like this.
551:19x 29
440:2x 2x 2x 5x 11
361:19x 19
312:2x 2x 2x 3x 13
270:2x 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 2x 3x 5x 19 = 4560
Therefore, the value for common factors is 4560.
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 = 7372755561600/(1x4560)
LCM = 7372755561600/4560
LCM = 1616832360
Thus, we can understand that the LCM of 551,440,361,312,270 is 1616832360.
