Given numbers are 559,686,688,561
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 559,686,688,561 is 1721031312.
Find LCM of 559,686,688,561 with Prime Factorization
| 2 | 559, 686, 688, 561 |
| 43 | 559, 343, 344, 561 |
| 13, 343, 8, 561 |
Multiply the prime numbers at the bottom and the left side.
2 x 43 x 13 x 343 x 8 x 561 = 1721031312
Therefore, the lowest common multiple of 559,686,688,561 is 1721031312.
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.
559 x 686 x 688 x 561 = 148008692832
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.
559 : 1, 13, 43, 559
686 : 1, 2, 7, 14, 49, 98, 343, 686
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
561 : 1, 3, 11, 17, 33, 51, 187, 561
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 559,686,688,561, is 1.
Now, the common factors can be found like this.
559:13x 43
686:2x 7x 7x 7
688:2x 2x 2x 2x 43
561:3x 11x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 43 = 86
Therefore, the value for common factors is 86.
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 = 148008692832/(1x86)
LCM = 148008692832/86
LCM = 1721031312
Thus, we can understand that the LCM of 559,686,688,561 is 1721031312.
