Find LCM of 819,431,943,754,153 with Prime Factorization
| 3 | 819, 431, 943, 754, 153 |
| 3 | 273, 431, 943, 754, 51 |
| 13 | 91, 431, 943, 754, 17 |
| 7, 431, 943, 58, 17 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 13 x 7 x 431 x 943 x 58 x 17 = 328208466222
Therefore, the lowest common multiple of 819,431,943,754,153 is 328208466222.
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.
819 x 431 x 943 x 754 x 153 = 38400390547974
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.
819 : 1, 3, 7, 9, 13, 21, 39, 63, 91, 117, 273, 819
431 : 1, 431
943 : 1, 23, 41, 943
754 : 1, 2, 13, 26, 29, 58, 377, 754
153 : 1, 3, 9, 17, 51, 153
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 819,431,943,754,153, is 1.
Now, the common factors can be found like this.
819:3x 3x 7x 13
431:431
943:23x 41
754:2x 13x 29
153:3x 3x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 13 = 117
Therefore, the value for common factors is 117.
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 = 38400390547974/(1x117)
LCM = 38400390547974/117
LCM = 328208466222
Thus, we can understand that the LCM of 819,431,943,754,153 is 328208466222.
