Given numbers are 865,915,457,173
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 865,915,457,173 is 72340815.
Find LCM of 865,915,457,173 with Prime Factorization
| 5 | 865, 915, 457, 173 |
| 173 | 173, 183, 457, 173 |
| 1, 183, 457, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 173 x 1 x 183 x 457 x 1 = 72340815
Therefore, the lowest common multiple of 865,915,457,173 is 72340815.
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 915 x 457 x 173 = 62574804975
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
915 : 1, 3, 5, 15, 61, 183, 305, 915
457 : 1, 457
173 : 1, 173
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 865,915,457,173, is 1.
Now, the common factors can be found like this.
865:5x 173
915:3x 5x 61
457:457
173:173
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 173 = 865
Therefore, the value for common factors is 865.
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 = 62574804975/(1x865)
LCM = 62574804975/865
LCM = 72340815
Thus, we can understand that the LCM of 865,915,457,173 is 72340815.
