Given numbers are 830,918,561,201
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 830,918,561,201 is 280774890.
Find LCM of 830,918,561,201 with Prime Factorization
| 2 | 830, 918, 561, 201 |
| 3 | 415, 459, 561, 201 |
| 17 | 415, 153, 187, 67 |
| 415, 9, 11, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 415 x 9 x 11 x 67 = 280774890
Therefore, the lowest common multiple of 830,918,561,201 is 280774890.
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.
830 x 918 x 561 x 201 = 85917116340
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.
830 : 1, 2, 5, 10, 83, 166, 415, 830
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
561 : 1, 3, 11, 17, 33, 51, 187, 561
201 : 1, 3, 67, 201
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 830,918,561,201, is 1.
Now, the common factors can be found like this.
830:2x 5x 83
918:2x 3x 3x 3x 17
561:3x 11x 17
201:3x 67
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 17 = 306
Therefore, the value for common factors is 306.
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 = 85917116340/(1x306)
LCM = 85917116340/306
LCM = 280774890
Thus, we can understand that the LCM of 830,918,561,201 is 280774890.
