Given numbers are 559,646,399,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 559,646,399,221 is 7583394.
Find LCM of 559,646,399,221 with Prime Factorization
| 13 | 559, 646, 399, 221 |
| 17 | 43, 646, 399, 17 |
| 19 | 43, 38, 399, 1 |
| 43, 2, 21, 1 |
Multiply the prime numbers at the bottom and the left side.
13 x 17 x 19 x 43 x 2 x 21 x 1 = 7583394
Therefore, the lowest common multiple of 559,646,399,221 is 7583394.
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 646 x 399 x 221 = 31842671406
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
646 : 1, 2, 17, 19, 34, 38, 323, 646
399 : 1, 3, 7, 19, 21, 57, 133, 399
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 559,646,399,221, is 1.
Now, the common factors can be found like this.
559:13x 43
646:2x 17x 19
399:3x 7x 19
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 17x 19 = 4199
Therefore, the value for common factors is 4199.
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 = 31842671406/(1x4199)
LCM = 31842671406/4199
LCM = 7583394
Thus, we can understand that the LCM of 559,646,399,221 is 7583394.
