Given numbers are 223,546,223,778,905
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 223,546,223,778,905 is 42864295110.
Find LCM of 223,546,223,778,905 with Prime Factorization
| 2 | 223, 546, 223, 778, 905 |
| 223 | 223, 273, 223, 389, 905 |
| 1, 273, 1, 389, 905 |
Multiply the prime numbers at the bottom and the left side.
2 x 223 x 1 x 273 x 1 x 389 x 905 = 42864295110
Therefore, the lowest common multiple of 223,546,223,778,905 is 42864295110.
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 546 x 223 x 778 x 905 = 19117475619060
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
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
223 : 1, 223
778 : 1, 2, 389, 778
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 223,546,223,778,905, is 1.
Now, the common factors can be found like this.
223:223
546:2x 3x 7x 13
223:223
778:2x 389
905:5x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 223 = 446
Therefore, the value for common factors is 446.
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 = 19117475619060/(1x446)
LCM = 19117475619060/446
LCM = 42864295110
Thus, we can understand that the LCM of 223,546,223,778,905 is 42864295110.
