Find LCM of 845,721,176,286,788 with Prime Factorization
2 | 845, 721, 176, 286, 788 |
2 | 845, 721, 88, 143, 394 |
11 | 845, 721, 44, 143, 197 |
13 | 845, 721, 4, 13, 197 |
65, 721, 4, 1, 197 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 13 x 65 x 721 x 4 x 1 x 197 = 21123742640
Therefore, the lowest common multiple of 845,721,176,286,788 is 21123742640.
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.
845 x 721 x 176 x 286 x 788 = 24165561580160
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.
845 : 1, 5, 13, 65, 169, 845
721 : 1, 7, 103, 721
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
286 : 1, 2, 11, 13, 22, 26, 143, 286
788 : 1, 2, 4, 197, 394, 788
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,721,176,286,788, is 1.
Now, the common factors can be found like this.
845:5x 13x 13
721:7x 103
176:2x 2x 2x 2x 11
286:2x 11x 13
788:2x 2x 197
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 11x 13 = 1144
Therefore, the value for common factors is 1144.
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 = 24165561580160/(1x1144)
LCM = 24165561580160/1144
LCM = 21123742640
Thus, we can understand that the LCM of 845,721,176,286,788 is 21123742640.
