Given numbers are 639,591,660,876,149
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,591,660,876,149 is 301230466020.
Find LCM of 639,591,660,876,149 with Prime Factorization
| 2 | 639, 591, 660, 876, 149 |
| 2 | 639, 591, 330, 438, 149 |
| 3 | 639, 591, 165, 219, 149 |
| 213, 197, 55, 73, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 213 x 197 x 55 x 73 x 149 = 301230466020
Therefore, the lowest common multiple of 639,591,660,876,149 is 301230466020.
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.
639 x 591 x 660 x 876 x 149 = 32532890330160
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.
639 : 1, 3, 9, 71, 213, 639
591 : 1, 3, 197, 591
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
149 : 1, 149
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,591,660,876,149, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
591:3x 197
660:2x 2x 3x 5x 11
876:2x 2x 3x 73
149:149
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 = 32532890330160/(1x108)
LCM = 32532890330160/108
LCM = 301230466020
Thus, we can understand that the LCM of 639,591,660,876,149 is 301230466020.
