Given numbers are 639,639,789,511,203
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,639,789,511,203 is 2490436683.
Find LCM of 639,639,789,511,203 with Prime Factorization
| 3 | 639, 639, 789, 511, 203 |
| 3 | 213, 213, 263, 511, 203 |
| 7 | 71, 71, 263, 511, 203 |
| 71 | 71, 71, 263, 73, 29 |
| 1, 1, 263, 73, 29 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 7 x 71 x 1 x 1 x 263 x 73 x 29 = 2490436683
Therefore, the lowest common multiple of 639,639,789,511,203 is 2490436683.
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 639 x 789 x 511 x 203 = 33419169849177
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
639 : 1, 3, 9, 71, 213, 639
789 : 1, 3, 263, 789
511 : 1, 7, 73, 511
203 : 1, 7, 29, 203
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,639,789,511,203, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
639:3x 3x 71
789:3x 263
511:7x 73
203:7x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 7x 71 = 13419
Therefore, the value for common factors is 13419.
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 = 33419169849177/(1x13419)
LCM = 33419169849177/13419
LCM = 2490436683
Thus, we can understand that the LCM of 639,639,789,511,203 is 2490436683.
