Find LCM of 675,917,621,926,686 with Prime Factorization
| 2 | 675, 917, 621, 926, 686 |
| 3 | 675, 917, 621, 463, 343 |
| 3 | 225, 917, 207, 463, 343 |
| 3 | 75, 917, 69, 463, 343 |
| 7 | 25, 917, 23, 463, 343 |
| 25, 131, 23, 463, 49 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 7 x 25 x 131 x 23 x 463 x 49 = 645963547950
Therefore, the lowest common multiple of 675,917,621,926,686 is 645963547950.
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.
675 x 917 x 621 x 926 x 686 = 244174221125100
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.
675 : 1, 3, 5, 9, 15, 25, 27, 45, 75, 135, 225, 675
917 : 1, 7, 131, 917
621 : 1, 3, 9, 23, 27, 69, 207, 621
926 : 1, 2, 463, 926
686 : 1, 2, 7, 14, 49, 98, 343, 686
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 675,917,621,926,686, is 1.
Now, the common factors can be found like this.
675:3x 3x 3x 5x 5
917:7x 131
621:3x 3x 3x 23
926:2x 463
686:2x 7x 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.
2x 3x 3x 3x 7 = 378
Therefore, the value for common factors is 378.
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 = 244174221125100/(1x378)
LCM = 244174221125100/378
LCM = 645963547950
Thus, we can understand that the LCM of 675,917,621,926,686 is 645963547950.
