Given numbers are 237,687,189,690,623
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 237,687,189,690,623 is 69991003530.
Find LCM of 237,687,189,690,623 with Prime Factorization
| 3 | 237, 687, 189, 690, 623 |
| 7 | 79, 229, 63, 230, 623 |
| 79, 229, 9, 230, 89 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 79 x 229 x 9 x 230 x 89 = 69991003530
Therefore, the lowest common multiple of 237,687,189,690,623 is 69991003530.
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.
237 x 687 x 189 x 690 x 623 = 13228299667170
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.
237 : 1, 3, 79, 237
687 : 1, 3, 229, 687
189 : 1, 3, 7, 9, 21, 27, 63, 189
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
623 : 1, 7, 89, 623
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 237,687,189,690,623, is 1.
Now, the common factors can be found like this.
237:3x 79
687:3x 229
189:3x 3x 3x 7
690:2x 3x 5x 23
623:7x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 7 = 189
Therefore, the value for common factors is 189.
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 = 13228299667170/(1x189)
LCM = 13228299667170/189
LCM = 69991003530
Thus, we can understand that the LCM of 237,687,189,690,623 is 69991003530.
