Find LCM of 309,829,424,400,981 with Prime Factorization
| 2 | 309, 829, 424, 400, 981 |
| 2 | 309, 829, 212, 200, 981 |
| 2 | 309, 829, 106, 100, 981 |
| 3 | 309, 829, 53, 50, 981 |
| 103, 829, 53, 50, 327 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 103 x 829 x 53 x 50 x 327 = 1775810516400
Therefore, the lowest common multiple of 309,829,424,400,981 is 1775810516400.
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.
309 x 829 x 424 x 400 x 981 = 42619452393600
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.
309 : 1, 3, 103, 309
829 : 1, 829
424 : 1, 2, 4, 8, 53, 106, 212, 424
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
981 : 1, 3, 9, 109, 327, 981
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 309,829,424,400,981, is 1.
Now, the common factors can be found like this.
309:3x 103
829:829
424:2x 2x 2x 53
400:2x 2x 2x 2x 5x 5
981:3x 3x 109
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 3 = 24
Therefore, the value for common factors is 24.
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 = 42619452393600/(1x24)
LCM = 42619452393600/24
LCM = 1775810516400
Thus, we can understand that the LCM of 309,829,424,400,981 is 1775810516400.
