Given numbers are 970,867,400,289
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 970,867,400,289 is 33639600.
Find LCM of 970,867,400,289 with Prime Factorization
| 2 | 970, 867, 400, 289 |
| 5 | 485, 867, 200, 289 |
| 17 | 97, 867, 40, 289 |
| 17 | 97, 51, 40, 17 |
| 97, 3, 40, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 17 x 97 x 3 x 40 x 1 = 33639600
Therefore, the lowest common multiple of 970,867,400,289 is 33639600.
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.
970 x 867 x 400 x 289 = 97218444000
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.
970 : 1, 2, 5, 10, 97, 194, 485, 970
867 : 1, 3, 17, 51, 289, 867
400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400
289 : 1, 17, 289
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 970,867,400,289, is 1.
Now, the common factors can be found like this.
970:2x 5x 97
867:3x 17x 17
400:2x 2x 2x 2x 5x 5
289:17x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 17x 17 = 2890
Therefore, the value for common factors is 2890.
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 = 97218444000/(1x2890)
LCM = 97218444000/2890
LCM = 33639600
Thus, we can understand that the LCM of 970,867,400,289 is 33639600.
