Given numbers are 330,103,128,492,395
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 330,103,128,492,395 is 7045991040.
Find LCM of 330,103,128,492,395 with Prime Factorization
| 2 | 330, 103, 128, 492, 395 |
| 2 | 165, 103, 64, 246, 395 |
| 3 | 165, 103, 32, 123, 395 |
| 5 | 55, 103, 32, 41, 395 |
| 11, 103, 32, 41, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 103 x 32 x 41 x 79 = 7045991040
Therefore, the lowest common multiple of 330,103,128,492,395 is 7045991040.
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 103 x 128 x 492 x 395 = 845518924800
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
103 : 1, 103
128 : 1, 2, 4, 8, 16, 32, 64, 128
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
395 : 1, 5, 79, 395
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 330,103,128,492,395, is 1.
Now, the common factors can be found like this.
330:2x 3x 5x 11
103:103
128:2x 2x 2x 2x 2x 2x 2
492:2x 2x 3x 41
395:5x 79
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 2x 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 845518924800/(1x120)
LCM = 845518924800/120
LCM = 7045991040
Thus, we can understand that the LCM of 330,103,128,492,395 is 7045991040.
