Given numbers are 551,559,169,399
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 551,559,169,399 is 84086457.
Find LCM of 551,559,169,399 with Prime Factorization
| 13 | 551, 559, 169, 399 |
| 19 | 551, 43, 13, 399 |
| 29, 43, 13, 21 |
Multiply the prime numbers at the bottom and the left side.
13 x 19 x 29 x 43 x 13 x 21 = 84086457
Therefore, the lowest common multiple of 551,559,169,399 is 84086457.
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.
551 x 559 x 169 x 399 = 20769354879
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.
551 : 1, 19, 29, 551
559 : 1, 13, 43, 559
169 : 1, 13, 169
399 : 1, 3, 7, 19, 21, 57, 133, 399
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 551,559,169,399, is 1.
Now, the common factors can be found like this.
551:19x 29
559:13x 43
169:13x 13
399:3x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13x 19 = 247
Therefore, the value for common factors is 247.
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 = 20769354879/(1x247)
LCM = 20769354879/247
LCM = 84086457
Thus, we can understand that the LCM of 551,559,169,399 is 84086457.
