Given numbers are 278,765,723,135,405
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 278,765,723,135,405 is 461281230.
Find LCM of 278,765,723,135,405 with Prime Factorization
| 3 | 278, 765, 723, 135, 405 |
| 3 | 278, 255, 241, 45, 135 |
| 3 | 278, 85, 241, 15, 45 |
| 5 | 278, 85, 241, 5, 15 |
| 278, 17, 241, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 3 x 5 x 278 x 17 x 241 x 1 x 3 = 461281230
Therefore, the lowest common multiple of 278,765,723,135,405 is 461281230.
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.
278 x 765 x 723 x 135 x 405 = 8406850416750
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.
278 : 1, 2, 139, 278
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
723 : 1, 3, 241, 723
135 : 1, 3, 5, 9, 15, 27, 45, 135
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 278,765,723,135,405, is 1.
Now, the common factors can be found like this.
278:2x 139
765:3x 3x 5x 17
723:3x 241
135:3x 3x 3x 5
405:3x 3x 3x 3x 5
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 3x 3x 3x 5x 5 = 18225
Therefore, the value for common factors is 18225.
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 = 8406850416750/(1x18225)
LCM = 8406850416750/18225
LCM = 461281230
Thus, we can understand that the LCM of 278,765,723,135,405 is 461281230.
