Find LCM of 931,682,646,286,392 with Prime Factorization
2 | 931, 682, 646, 286, 392 |
7 | 931, 341, 323, 143, 196 |
7 | 133, 341, 323, 143, 28 |
11 | 19, 341, 323, 143, 4 |
19 | 19, 31, 323, 13, 4 |
1, 31, 17, 13, 4 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 7 x 11 x 19 x 1 x 31 x 17 x 13 x 4 = 561288728
Therefore, the lowest common multiple of 931,682,646,286,392 is 561288728.
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.
931 x 682 x 646 x 286 x 392 = 45985262907584
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.
931 : 1, 7, 19, 49, 133, 931
682 : 1, 2, 11, 22, 31, 62, 341, 682
646 : 1, 2, 17, 19, 34, 38, 323, 646
286 : 1, 2, 11, 13, 22, 26, 143, 286
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 931,682,646,286,392, is 1.
Now, the common factors can be found like this.
931:7x 7x 19
682:2x 11x 31
646:2x 17x 19
286:2x 11x 13
392:2x 2x 2x 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 2x 2x 7x 7x 11x 19 = 81928
Therefore, the value for common factors is 81928.
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 = 45985262907584/(1x81928)
LCM = 45985262907584/81928
LCM = 561288728
Thus, we can understand that the LCM of 931,682,646,286,392 is 561288728.
