Find LCM of 706,115,808,442,690 with Prime Factorization
2 | 706, 115, 808, 442, 690 |
5 | 353, 115, 404, 221, 345 |
23 | 353, 23, 404, 221, 69 |
353, 1, 404, 221, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 23 x 353 x 1 x 404 x 221 x 3 = 21746903880
Therefore, the lowest common multiple of 706,115,808,442,690 is 21746903880.
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.
706 x 115 x 808 x 442 x 690 = 20007151569600
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.
706 : 1, 2, 353, 706
115 : 1, 5, 23, 115
808 : 1, 2, 4, 8, 101, 202, 404, 808
442 : 1, 2, 13, 17, 26, 34, 221, 442
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 706,115,808,442,690, is 1.
Now, the common factors can be found like this.
706:2x 353
115:5x 23
808:2x 2x 2x 101
442:2x 13x 17
690:2x 3x 5x 23
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 5x 23 = 920
Therefore, the value for common factors is 920.
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 = 20007151569600/(1x920)
LCM = 20007151569600/920
LCM = 21746903880
Thus, we can understand that the LCM of 706,115,808,442,690 is 21746903880.
