Given numbers are 108,789,117,338
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 108,789,117,338 is 4800276.
Find LCM of 108,789,117,338 with Prime Factorization
| 2 | 108, 789, 117, 338 |
| 3 | 54, 789, 117, 169 |
| 3 | 18, 263, 39, 169 |
| 13 | 6, 263, 13, 169 |
| 6, 263, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 13 x 6 x 263 x 1 x 13 = 4800276
Therefore, the lowest common multiple of 108,789,117,338 is 4800276.
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.
108 x 789 x 117 x 338 = 3369793752
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.
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
789 : 1, 3, 263, 789
117 : 1, 3, 9, 13, 39, 117
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 108,789,117,338, is 1.
Now, the common factors can be found like this.
108:2x 2x 3x 3x 3
789:3x 263
117:3x 3x 13
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 3x 3x 3x 13 = 702
Therefore, the value for common factors is 702.
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 = 3369793752/(1x702)
LCM = 3369793752/702
LCM = 4800276
Thus, we can understand that the LCM of 108,789,117,338 is 4800276.
