Find LCM of 441,342,675,686,454 with Prime Factorization
| 2 | 441, 342, 675, 686, 454 |
| 3 | 441, 171, 675, 343, 227 |
| 3 | 147, 57, 225, 343, 227 |
| 7 | 49, 19, 75, 343, 227 |
| 7 | 7, 19, 75, 49, 227 |
| 1, 19, 75, 7, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 7 x 1 x 19 x 75 x 7 x 227 = 1997134650
Therefore, the lowest common multiple of 441,342,675,686,454 is 1997134650.
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.
441 x 342 x 675 x 686 x 454 = 31706509703400
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.
441 : 1, 3, 7, 9, 21, 49, 63, 147, 441
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
686 : 1, 2, 7, 14, 49, 98, 343, 686
454 : 1, 2, 227, 454
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 441,342,675,686,454, is 1.
Now, the common factors can be found like this.
441:3x 3x 7x 7
342:2x 3x 3x 19
675:3x 3x 3x 5x 5
686:2x 7x 7x 7
454:2x 227
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 3x 3x 3x 3x 7x 7 = 15876
Therefore, the value for common factors is 15876.
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 = 31706509703400/(1x15876)
LCM = 31706509703400/15876
LCM = 1997134650
Thus, we can understand that the LCM of 441,342,675,686,454 is 1997134650.
