Find LCM of 441,279,924,686 with Prime Factorization
| 2 | 441, 279, 924, 686 |
| 3 | 441, 279, 462, 343 |
| 3 | 147, 93, 154, 343 |
| 7 | 49, 31, 154, 343 |
| 7 | 7, 31, 22, 49 |
| 1, 31, 22, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 7 x 1 x 31 x 22 x 7 = 4210668
Therefore, the lowest common multiple of 441,279,924,686 is 4210668.
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 279 x 924 x 686 = 77989992696
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
279 : 1, 3, 9, 31, 93, 279
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
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 441,279,924,686, is 1.
Now, the common factors can be found like this.
441:3x 3x 7x 7
279:3x 3x 31
924:2x 2x 3x 7x 11
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 7x 7x 7 = 18522
Therefore, the value for common factors is 18522.
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 = 77989992696/(1x18522)
LCM = 77989992696/18522
LCM = 4210668
Thus, we can understand that the LCM of 441,279,924,686 is 4210668.
