Given numbers are 330,177,397,644,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 330,177,397,644,638 is 72178911420.
Find LCM of 330,177,397,644,638 with Prime Factorization
| 2 | 330, 177, 397, 644, 638 |
| 3 | 165, 177, 397, 322, 319 |
| 11 | 55, 59, 397, 322, 319 |
| 5, 59, 397, 322, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 5 x 59 x 397 x 322 x 29 = 72178911420
Therefore, the lowest common multiple of 330,177,397,644,638 is 72178911420.
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.
330 x 177 x 397 x 644 x 638 = 9527616307440
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.
330 : 1, 2, 3, 5, 6, 10, 11, 15, 22, 30, 33, 55, 66, 110, 165, 330
177 : 1, 3, 59, 177
397 : 1, 397
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 330,177,397,644,638, is 1.
Now, the common factors can be found like this.
330:2x 3x 5x 11
177:3x 59
397:397
644:2x 2x 7x 23
638:2x 11x 29
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 11 = 132
Therefore, the value for common factors is 132.
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 = 9527616307440/(1x132)
LCM = 9527616307440/132
LCM = 72178911420
Thus, we can understand that the LCM of 330,177,397,644,638 is 72178911420.
