Given numbers are 159,405,126,503,278
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 159,405,126,503,278 is 21010757670.
Find LCM of 159,405,126,503,278 with Prime Factorization
| 2 | 159, 405, 126, 503, 278 |
| 3 | 159, 405, 63, 503, 139 |
| 3 | 53, 135, 21, 503, 139 |
| 53, 45, 7, 503, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 53 x 45 x 7 x 503 x 139 = 21010757670
Therefore, the lowest common multiple of 159,405,126,503,278 is 21010757670.
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.
159 x 405 x 126 x 503 x 278 = 1134580914180
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.
159 : 1, 3, 53, 159
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
503 : 1, 503
278 : 1, 2, 139, 278
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 159,405,126,503,278, is 1.
Now, the common factors can be found like this.
159:3x 53
405:3x 3x 3x 3x 5
126:2x 3x 3x 7
503:503
278:2x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 1134580914180/(1x54)
LCM = 1134580914180/54
LCM = 21010757670
Thus, we can understand that the LCM of 159,405,126,503,278 is 21010757670.
