Given numbers are 860,982,172
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 860,982,172 is 422260.
Find LCM of 860,982,172 with Prime Factorization
| 2 | 860, 982, 172 |
| 2 | 430, 491, 86 |
| 43 | 215, 491, 43 |
| 5, 491, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 43 x 5 x 491 x 1 = 422260
Therefore, the lowest common multiple of 860,982,172 is 422260.
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.
860 x 982 x 172 = 145257440
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.
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
982 : 1, 2, 491, 982
172 : 1, 2, 4, 43, 86, 172
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 860,982,172, is 2.
Now, the common factors can be found like this.
860:2x 2x 5x 43
982:2x 491
172:2x 2x 43
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 43 = 172
Therefore, the value for common factors is 172.
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 = 145257440/(2x172)
LCM = 145257440/344
LCM = 422260
Thus, we can understand that the LCM of 860,982,172 is 422260.
