Given numbers are 249,890,385,520,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 249,890,385,520,621 is 183676573080.
Find LCM of 249,890,385,520,621 with Prime Factorization
| 2 | 249, 890, 385, 520, 621 |
| 3 | 249, 445, 385, 260, 621 |
| 5 | 83, 445, 385, 260, 207 |
| 83, 89, 77, 52, 207 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 83 x 89 x 77 x 52 x 207 = 183676573080
Therefore, the lowest common multiple of 249,890,385,520,621 is 183676573080.
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.
249 x 890 x 385 x 520 x 621 = 27551485962000
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.
249 : 1, 3, 83, 249
890 : 1, 2, 5, 10, 89, 178, 445, 890
385 : 1, 5, 7, 11, 35, 55, 77, 385
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 249,890,385,520,621, is 1.
Now, the common factors can be found like this.
249:3x 83
890:2x 5x 89
385:5x 7x 11
520:2x 2x 2x 5x 13
621:3x 3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 5 = 150
Therefore, the value for common factors is 150.
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 = 27551485962000/(1x150)
LCM = 27551485962000/150
LCM = 183676573080
Thus, we can understand that the LCM of 249,890,385,520,621 is 183676573080.
