Given numbers are 223,855,331,778,639
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 223,855,331,778,639 is 3486076532370.
Find LCM of 223,855,331,778,639 with Prime Factorization
| 3 | 223, 855, 331, 778, 639 |
| 3 | 223, 285, 331, 778, 213 |
| 223, 95, 331, 778, 71 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 223 x 95 x 331 x 778 x 71 = 3486076532370
Therefore, the lowest common multiple of 223,855,331,778,639 is 3486076532370.
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.
223 x 855 x 331 x 778 x 639 = 31374688791330
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.
223 : 1, 223
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
331 : 1, 331
778 : 1, 2, 389, 778
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 223,855,331,778,639, is 1.
Now, the common factors can be found like this.
223:223
855:3x 3x 5x 19
331:331
778:2x 389
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3 = 9
Therefore, the value for common factors is 9.
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 = 31374688791330/(1x9)
LCM = 31374688791330/9
LCM = 3486076532370
Thus, we can understand that the LCM of 223,855,331,778,639 is 3486076532370.
