Given numbers are 834,561,275,775
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 834,561,275,775 is 120867450.
Find LCM of 834,561,275,775 with Prime Factorization
| 3 | 834, 561, 275, 775 |
| 5 | 278, 187, 275, 775 |
| 5 | 278, 187, 55, 155 |
| 11 | 278, 187, 11, 31 |
| 278, 17, 1, 31 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 5 x 11 x 278 x 17 x 1 x 31 = 120867450
Therefore, the lowest common multiple of 834,561,275,775 is 120867450.
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.
834 x 561 x 275 x 775 = 99715646250
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.
834 : 1, 2, 3, 6, 139, 278, 417, 834
561 : 1, 3, 11, 17, 33, 51, 187, 561
275 : 1, 5, 11, 25, 55, 275
775 : 1, 5, 25, 31, 155, 775
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 834,561,275,775, is 1.
Now, the common factors can be found like this.
834:2x 3x 139
561:3x 11x 17
275:5x 5x 11
775:5x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 11 = 825
Therefore, the value for common factors is 825.
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 = 99715646250/(1x825)
LCM = 99715646250/825
LCM = 120867450
Thus, we can understand that the LCM of 834,561,275,775 is 120867450.
