Given numbers are 450,661,403,993,403
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 450,661,403,993,403 is 39677747850.
Find LCM of 450,661,403,993,403 with Prime Factorization
| 3 | 450, 661, 403, 993, 403 |
| 13 | 150, 661, 403, 331, 403 |
| 31 | 150, 661, 31, 331, 31 |
| 150, 661, 1, 331, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 31 x 150 x 661 x 1 x 331 x 1 = 39677747850
Therefore, the lowest common multiple of 450,661,403,993,403 is 39677747850.
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 661 x 403 x 993 x 403 = 47970397150650
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
661 : 1, 661
403 : 1, 13, 31, 403
993 : 1, 3, 331, 993
403 : 1, 13, 31, 403
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 450,661,403,993,403, is 1.
Now, the common factors can be found like this.
450:2x 3x 3x 5x 5
661:661
403:13x 31
993:3x 331
403:13x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 31 = 1209
Therefore, the value for common factors is 1209.
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 = 47970397150650/(1x1209)
LCM = 47970397150650/1209
LCM = 39677747850
Thus, we can understand that the LCM of 450,661,403,993,403 is 39677747850.
