Given numbers are 203,551,686,217
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 203,551,686,217 is 11717566.
Find LCM of 203,551,686,217 with Prime Factorization
| 7 | 203, 551, 686, 217 |
| 29 | 29, 551, 98, 31 |
| 1, 19, 98, 31 |
Multiply the prime numbers at the bottom and the left side.
7 x 29 x 1 x 19 x 98 x 31 = 11717566
Therefore, the lowest common multiple of 203,551,686,217 is 11717566.
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.
203 x 551 x 686 x 217 = 16650661286
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.
203 : 1, 7, 29, 203
551 : 1, 19, 29, 551
686 : 1, 2, 7, 14, 49, 98, 343, 686
217 : 1, 7, 31, 217
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 203,551,686,217, is 1.
Now, the common factors can be found like this.
203:7x 29
551:19x 29
686:2x 7x 7x 7
217:7x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7x 29 = 1421
Therefore, the value for common factors is 1421.
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 = 16650661286/(1x1421)
LCM = 16650661286/1421
LCM = 11717566
Thus, we can understand that the LCM of 203,551,686,217 is 11717566.
