Given numbers are 897,120,290,662,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 897,120,290,662,905 is 62338593720.
Find LCM of 897,120,290,662,905 with Prime Factorization
| 2 | 897, 120, 290, 662, 905 |
| 3 | 897, 60, 145, 331, 905 |
| 5 | 299, 20, 145, 331, 905 |
| 299, 4, 29, 331, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 299 x 4 x 29 x 331 x 181 = 62338593720
Therefore, the lowest common multiple of 897,120,290,662,905 is 62338593720.
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.
897 x 120 x 290 x 662 x 905 = 18701578116000
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.
897 : 1, 3, 13, 23, 39, 69, 299, 897
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
290 : 1, 2, 5, 10, 29, 58, 145, 290
662 : 1, 2, 331, 662
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,120,290,662,905, is 1.
Now, the common factors can be found like this.
897:3x 13x 23
120:2x 2x 2x 3x 5
290:2x 5x 29
662:2x 331
905:5x 181
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 3x 5x 5 = 300
Therefore, the value for common factors is 300.
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 = 18701578116000/(1x300)
LCM = 18701578116000/300
LCM = 62338593720
Thus, we can understand that the LCM of 897,120,290,662,905 is 62338593720.
