Given numbers are 865,185,624,185,687
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 865,185,624,185,687 is 4573386480.
Find LCM of 865,185,624,185,687 with Prime Factorization
| 3 | 865, 185, 624, 185, 687 |
| 5 | 865, 185, 208, 185, 229 |
| 37 | 173, 37, 208, 37, 229 |
| 173, 1, 208, 1, 229 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 37 x 173 x 1 x 208 x 1 x 229 = 4573386480
Therefore, the lowest common multiple of 865,185,624,185,687 is 4573386480.
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.
865 x 185 x 624 x 185 x 687 = 12691147482000
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.
865 : 1, 5, 173, 865
185 : 1, 5, 37, 185
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
185 : 1, 5, 37, 185
687 : 1, 3, 229, 687
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,185,624,185,687, is 1.
Now, the common factors can be found like this.
865:5x 173
185:5x 37
624:2x 2x 2x 2x 3x 13
185:5x 37
687:3x 229
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 37 = 2775
Therefore, the value for common factors is 2775.
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 = 12691147482000/(1x2775)
LCM = 12691147482000/2775
LCM = 4573386480
Thus, we can understand that the LCM of 865,185,624,185,687 is 4573386480.
