Given numbers are 475,685,133,287
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 475,685,133,287 is 18676525.
Find LCM of 475,685,133,287 with Prime Factorization
| 5 | 475, 685, 133, 287 |
| 7 | 95, 137, 133, 287 |
| 19 | 95, 137, 19, 41 |
| 5, 137, 1, 41 |
Multiply the prime numbers at the bottom and the left side.
5 x 7 x 19 x 5 x 137 x 1 x 41 = 18676525
Therefore, the lowest common multiple of 475,685,133,287 is 18676525.
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.
475 x 685 x 133 x 287 = 12419889125
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.
475 : 1, 5, 19, 25, 95, 475
685 : 1, 5, 137, 685
133 : 1, 7, 19, 133
287 : 1, 7, 41, 287
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 475,685,133,287, is 1.
Now, the common factors can be found like this.
475:5x 5x 19
685:5x 137
133:7x 19
287:7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 7x 19 = 665
Therefore, the value for common factors is 665.
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 = 12419889125/(1x665)
LCM = 12419889125/665
LCM = 18676525
Thus, we can understand that the LCM of 475,685,133,287 is 18676525.
