Given numbers are 338,254,378,486
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 338,254,378,486 is 73017126.
Find LCM of 338,254,378,486 with Prime Factorization
| 2 | 338, 254, 378, 486 |
| 3 | 169, 127, 189, 243 |
| 3 | 169, 127, 63, 81 |
| 3 | 169, 127, 21, 27 |
| 169, 127, 7, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 169 x 127 x 7 x 9 = 73017126
Therefore, the lowest common multiple of 338,254,378,486 is 73017126.
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.
338 x 254 x 378 x 486 = 15771699216
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.
338 : 1, 2, 13, 26, 169, 338
254 : 1, 2, 127, 254
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 338,254,378,486, is 2.
Now, the common factors can be found like this.
338:2x 13x 13
254:2x 127
378:2x 3x 3x 3x 7
486:2x 3x 3x 3x 3x 3
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 3 = 108
Therefore, the value for common factors is 108.
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 = 15771699216/(2x108)
LCM = 15771699216/216
LCM = 73017126
Thus, we can understand that the LCM of 338,254,378,486 is 73017126.
