Given numbers are 551,176,361,338
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 551,176,361,338 is 311389936.
Find LCM of 551,176,361,338 with Prime Factorization
| 2 | 551, 176, 361, 338 |
| 19 | 551, 88, 361, 169 |
| 29, 88, 19, 169 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 29 x 88 x 19 x 169 = 311389936
Therefore, the lowest common multiple of 551,176,361,338 is 311389936.
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.
551 x 176 x 361 x 338 = 11832817568
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.
551 : 1, 19, 29, 551
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
361 : 1, 19, 361
338 : 1, 2, 13, 26, 169, 338
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,176,361,338, is 1.
Now, the common factors can be found like this.
551:19x 29
176:2x 2x 2x 2x 11
361:19x 19
338:2x 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 19 = 38
Therefore, the value for common factors is 38.
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 = 11832817568/(1x38)
LCM = 11832817568/38
LCM = 311389936
Thus, we can understand that the LCM of 551,176,361,338 is 311389936.
