Given numbers are 633,771,815,378
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 633,771,815,378 is 16705711890.
Find LCM of 633,771,815,378 with Prime Factorization
| 3 | 633, 771, 815, 378 |
| 211, 257, 815, 126 |
Multiply the prime numbers at the bottom and the left side.
3 x 211 x 257 x 815 x 126 = 16705711890
Therefore, the lowest common multiple of 633,771,815,378 is 16705711890.
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.
633 x 771 x 815 x 378 = 150351407010
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.
633 : 1, 3, 211, 633
771 : 1, 3, 257, 771
815 : 1, 5, 163, 815
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 633,771,815,378, is 1.
Now, the common factors can be found like this.
633:3x 211
771:3x 257
815:5x 163
378:2x 3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 150351407010/(1x9)
LCM = 150351407010/9
LCM = 16705711890
Thus, we can understand that the LCM of 633,771,815,378 is 16705711890.
