Given numbers are 450,403,728,997,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 450,403,728,997,821 is 4156367178600.
Find LCM of 450,403,728,997,821 with Prime Factorization
| 2 | 450, 403, 728, 997, 821 |
| 13 | 225, 403, 364, 997, 821 |
| 225, 31, 28, 997, 821 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 225 x 31 x 28 x 997 x 821 = 4156367178600
Therefore, the lowest common multiple of 450,403,728,997,821 is 4156367178600.
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.
450 x 403 x 728 x 997 x 821 = 108065546643600
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.
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
403 : 1, 13, 31, 403
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
997 : 1, 997
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 450,403,728,997,821, is 1.
Now, the common factors can be found like this.
450:2x 3x 3x 5x 5
403:13x 31
728:2x 2x 2x 7x 13
997:997
821:821
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 108065546643600/(1x26)
LCM = 108065546643600/26
LCM = 4156367178600
Thus, we can understand that the LCM of 450,403,728,997,821 is 4156367178600.
