Find LCM of 438,351,802,351,398 with Prime Factorization
| 2 | 438, 351, 802, 351, 398 |
| 3 | 219, 351, 401, 351, 199 |
| 3 | 73, 117, 401, 117, 199 |
| 3 | 73, 39, 401, 39, 199 |
| 13 | 73, 13, 401, 13, 199 |
| 73, 1, 401, 1, 199 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 13 x 73 x 1 x 401 x 1 x 199 = 4089379554
Therefore, the lowest common multiple of 438,351,802,351,398 is 4089379554.
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.
438 x 351 x 802 x 351 x 398 = 17224466681448
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.
438 : 1, 2, 3, 6, 73, 146, 219, 438
351 : 1, 3, 9, 13, 27, 39, 117, 351
802 : 1, 2, 401, 802
351 : 1, 3, 9, 13, 27, 39, 117, 351
398 : 1, 2, 199, 398
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,351,802,351,398, is 1.
Now, the common factors can be found like this.
438:2x 3x 73
351:3x 3x 3x 13
802:2x 401
351:3x 3x 3x 13
398:2x 199
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 3x 3x 3x 3x 13 = 4212
Therefore, the value for common factors is 4212.
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 = 17224466681448/(1x4212)
LCM = 17224466681448/4212
LCM = 4089379554
Thus, we can understand that the LCM of 438,351,802,351,398 is 4089379554.
