Find LCM of 155,351,452,646,621 with Prime Factorization
| 2 | 155, 351, 452, 646, 621 |
| 3 | 155, 351, 226, 323, 621 |
| 3 | 155, 117, 226, 323, 207 |
| 3 | 155, 39, 226, 323, 69 |
| 155, 13, 226, 323, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 155 x 13 x 226 x 323 x 23 = 182686984740
Therefore, the lowest common multiple of 155,351,452,646,621 is 182686984740.
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.
155 x 351 x 452 x 646 x 621 = 9865097175960
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.
155 : 1, 5, 31, 155
351 : 1, 3, 9, 13, 27, 39, 117, 351
452 : 1, 2, 4, 113, 226, 452
646 : 1, 2, 17, 19, 34, 38, 323, 646
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,351,452,646,621, is 1.
Now, the common factors can be found like this.
155:5x 31
351:3x 3x 3x 13
452:2x 2x 113
646:2x 17x 19
621:3x 3x 3x 23
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 3 = 54
Therefore, the value for common factors is 54.
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 = 9865097175960/(1x54)
LCM = 9865097175960/54
LCM = 182686984740
Thus, we can understand that the LCM of 155,351,452,646,621 is 182686984740.
