Given numbers are 378,258,438,603
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 378,258,438,603 is 79498314.
Find LCM of 378,258,438,603 with Prime Factorization
| 2 | 378, 258, 438, 603 |
| 3 | 189, 129, 219, 603 |
| 3 | 63, 43, 73, 201 |
| 21, 43, 73, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 21 x 43 x 73 x 67 = 79498314
Therefore, the lowest common multiple of 378,258,438,603 is 79498314.
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.
378 x 258 x 438 x 603 = 25757453736
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.
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
258 : 1, 2, 3, 6, 43, 86, 129, 258
438 : 1, 2, 3, 6, 73, 146, 219, 438
603 : 1, 3, 9, 67, 201, 603
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 378,258,438,603, is 3.
Now, the common factors can be found like this.
378:2x 3x 3x 3x 7
258:2x 3x 43
438:2x 3x 73
603:3x 3x 67
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 = 25757453736/(3x108)
LCM = 25757453736/324
LCM = 79498314
Thus, we can understand that the LCM of 378,258,438,603 is 79498314.
