Given numbers are 223,458,163,686,771
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 223,458,163,686,771 is 4402571760426.
Find LCM of 223,458,163,686,771 with Prime Factorization
| 2 | 223, 458, 163, 686, 771 |
| 223, 229, 163, 343, 771 |
Multiply the prime numbers at the bottom and the left side.
2 x 223 x 229 x 163 x 343 x 771 = 4402571760426
Therefore, the lowest common multiple of 223,458,163,686,771 is 4402571760426.
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 458 x 163 x 686 x 771 = 8805143520852
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
458 : 1, 2, 229, 458
163 : 1, 163
686 : 1, 2, 7, 14, 49, 98, 343, 686
771 : 1, 3, 257, 771
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 223,458,163,686,771, is 1.
Now, the common factors can be found like this.
223:223
458:2x 229
163:163
686:2x 7x 7x 7
771:3x 257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 8805143520852/(1x2)
LCM = 8805143520852/2
LCM = 4402571760426
Thus, we can understand that the LCM of 223,458,163,686,771 is 4402571760426.
