Find LCM of 981,748,762,544,169 with Prime Factorization
| 2 | 981, 748, 762, 544, 169 |
| 2 | 981, 374, 381, 272, 169 |
| 3 | 981, 187, 381, 136, 169 |
| 17 | 327, 187, 127, 136, 169 |
| 327, 11, 127, 8, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 17 x 327 x 11 x 127 x 8 x 169 = 125994334752
Therefore, the lowest common multiple of 981,748,762,544,169 is 125994334752.
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.
981 x 748 x 762 x 544 x 169 = 51405688578816
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.
981 : 1, 3, 9, 109, 327, 981
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
762 : 1, 2, 3, 6, 127, 254, 381, 762
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
169 : 1, 13, 169
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 981,748,762,544,169, is 1.
Now, the common factors can be found like this.
981:3x 3x 109
748:2x 2x 11x 17
762:2x 3x 127
544:2x 2x 2x 2x 2x 17
169:13x 13
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 3x 17 = 408
Therefore, the value for common factors is 408.
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 = 51405688578816/(1x408)
LCM = 51405688578816/408
LCM = 125994334752
Thus, we can understand that the LCM of 981,748,762,544,169 is 125994334752.
