Given numbers are 543,721,172,817,427
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 543,721,172,817,427 is 78045340044.
Find LCM of 543,721,172,817,427 with Prime Factorization
| 7 | 543, 721, 172, 817, 427 |
| 43 | 543, 103, 172, 817, 61 |
| 543, 103, 4, 19, 61 |
Multiply the prime numbers at the bottom and the left side.
7 x 43 x 543 x 103 x 4 x 19 x 61 = 78045340044
Therefore, the lowest common multiple of 543,721,172,817,427 is 78045340044.
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.
543 x 721 x 172 x 817 x 427 = 23491647353244
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.
543 : 1, 3, 181, 543
721 : 1, 7, 103, 721
172 : 1, 2, 4, 43, 86, 172
817 : 1, 19, 43, 817
427 : 1, 7, 61, 427
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 543,721,172,817,427, is 1.
Now, the common factors can be found like this.
543:3x 181
721:7x 103
172:2x 2x 43
817:19x 43
427:7x 61
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 43 = 301
Therefore, the value for common factors is 301.
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 = 23491647353244/(1x301)
LCM = 23491647353244/301
LCM = 78045340044
Thus, we can understand that the LCM of 543,721,172,817,427 is 78045340044.
