Given numbers are 641,396,606,162,662
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 641,396,606,162,662 is 76373921844.
Find LCM of 641,396,606,162,662 with Prime Factorization
| 2 | 641, 396, 606, 162, 662 |
| 3 | 641, 198, 303, 81, 331 |
| 3 | 641, 66, 101, 27, 331 |
| 641, 22, 101, 9, 331 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 641 x 22 x 101 x 9 x 331 = 76373921844
Therefore, the lowest common multiple of 641,396,606,162,662 is 76373921844.
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.
641 x 396 x 606 x 162 x 662 = 16496767118304
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.
641 : 1, 641
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
606 : 1, 2, 3, 6, 101, 202, 303, 606
162 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162
662 : 1, 2, 331, 662
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 641,396,606,162,662, is 1.
Now, the common factors can be found like this.
641:641
396:2x 2x 3x 3x 11
606:2x 3x 101
162:2x 3x 3x 3x 3
662:2x 331
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 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 16496767118304/(1x216)
LCM = 16496767118304/216
LCM = 76373921844
Thus, we can understand that the LCM of 641,396,606,162,662 is 76373921844.
