Find LCM of 561,718,897,157,442 with Prime Factorization
| 2 | 561, 718, 897, 157, 442 |
| 3 | 561, 359, 897, 157, 221 |
| 13 | 187, 359, 299, 157, 221 |
| 17 | 187, 359, 23, 157, 17 |
| 11, 359, 23, 157, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 17 x 11 x 359 x 23 x 157 x 1 = 18908546514
Therefore, the lowest common multiple of 561,718,897,157,442 is 18908546514.
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.
561 x 718 x 897 x 157 x 442 = 25072732677564
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
718 : 1, 2, 359, 718
897 : 1, 3, 13, 23, 39, 69, 299, 897
157 : 1, 157
442 : 1, 2, 13, 17, 26, 34, 221, 442
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,718,897,157,442, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
718:2x 359
897:3x 13x 23
157:157
442:2x 13x 17
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 13x 17 = 1326
Therefore, the value for common factors is 1326.
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 = 25072732677564/(1x1326)
LCM = 25072732677564/1326
LCM = 18908546514
Thus, we can understand that the LCM of 561,718,897,157,442 is 18908546514.
