Find LCM of 431,357,315,221,330 with Prime Factorization
| 3 | 431, 357, 315, 221, 330 |
| 5 | 431, 119, 105, 221, 110 |
| 7 | 431, 119, 21, 221, 22 |
| 17 | 431, 17, 3, 221, 22 |
| 431, 1, 3, 13, 22 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 7 x 17 x 431 x 1 x 3 x 13 x 22 = 660089430
Therefore, the lowest common multiple of 431,357,315,221,330 is 660089430.
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.
431 x 357 x 315 x 221 x 330 = 3534778897650
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.
431 : 1, 431
357 : 1, 3, 7, 17, 21, 51, 119, 357
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
221 : 1, 13, 17, 221
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 431,357,315,221,330, is 1.
Now, the common factors can be found like this.
431:431
357:3x 7x 17
315:3x 3x 5x 7
221:13x 17
330:2x 3x 5x 11
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 5x 7x 17 = 5355
Therefore, the value for common factors is 5355.
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 = 3534778897650/(1x5355)
LCM = 3534778897650/5355
LCM = 660089430
Thus, we can understand that the LCM of 431,357,315,221,330 is 660089430.
