Given numbers are 490,782,450,873
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 490,782,450,873 is 836290350.
Find LCM of 490,782,450,873 with Prime Factorization
| 2 | 490, 782, 450, 873 |
| 3 | 245, 391, 225, 873 |
| 3 | 245, 391, 75, 291 |
| 5 | 245, 391, 25, 97 |
| 49, 391, 5, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 49 x 391 x 5 x 97 = 836290350
Therefore, the lowest common multiple of 490,782,450,873 is 836290350.
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.
490 x 782 x 450 x 873 = 150532263000
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.
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
782 : 1, 2, 17, 23, 34, 46, 391, 782
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
873 : 1, 3, 9, 97, 291, 873
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 490,782,450,873, is 1.
Now, the common factors can be found like this.
490:2x 5x 7x 7
782:2x 17x 23
450:2x 3x 3x 5x 5
873:3x 3x 97
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 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 150532263000/(1x180)
LCM = 150532263000/180
LCM = 836290350
Thus, we can understand that the LCM of 490,782,450,873 is 836290350.
