Find LCM of 991,219,494,663,906 with Prime Factorization
2 | 991, 219, 494, 663, 906 |
3 | 991, 219, 247, 663, 453 |
13 | 991, 73, 247, 221, 151 |
991, 73, 19, 17, 151 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 991 x 73 x 19 x 17 x 151 = 275214040842
Therefore, the lowest common multiple of 991,219,494,663,906 is 275214040842.
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.
991 x 219 x 494 x 663 x 906 = 64400085557028
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.
991 : 1, 991
219 : 1, 3, 73, 219
494 : 1, 2, 13, 19, 26, 38, 247, 494
663 : 1, 3, 13, 17, 39, 51, 221, 663
906 : 1, 2, 3, 6, 151, 302, 453, 906
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 991,219,494,663,906, is 1.
Now, the common factors can be found like this.
991:991
219:3x 73
494:2x 13x 19
663:3x 13x 17
906:2x 3x 151
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 13 = 234
Therefore, the value for common factors is 234.
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 = 64400085557028/(1x234)
LCM = 64400085557028/234
LCM = 275214040842
Thus, we can understand that the LCM of 991,219,494,663,906 is 275214040842.
