Given numbers are 9,685,560,665
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 9,685,560,665 is 13119120.
Find LCM of 9,685,560,665 with Prime Factorization
| 5 | 9, 685, 560, 665 |
| 7 | 9, 137, 112, 133 |
| 9, 137, 16, 19 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 9 x 137 x 16 x 19 = 13119120
Therefore, the lowest common multiple of 9,685,560,665 is 13119120.
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.
9 x 685 x 560 x 665 = 2295846000
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.
9 : 1, 3, 9
685 : 1, 5, 137, 685
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
665 : 1, 5, 7, 19, 35, 95, 133, 665
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 9,685,560,665, is 1.
Now, the common factors can be found like this.
9:3x 3
685:5x 137
560:2x 2x 2x 2x 5x 7
665:5x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 5x 7 = 175
Therefore, the value for common factors is 175.
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 = 2295846000/(1x175)
LCM = 2295846000/175
LCM = 13119120
Thus, we can understand that the LCM of 9,685,560,665 is 13119120.
