Given numbers are 223,618,605,721
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 223,618,605,721 is 583642290.
Find LCM of 223,618,605,721 with Prime Factorization
| 103 | 223, 618, 605, 721 |
| 223, 6, 605, 7 |
Multiply the prime numbers at the bottom and the left side.
103 x 223 x 6 x 605 x 7 = 583642290
Therefore, the lowest common multiple of 223,618,605,721 is 583642290.
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 618 x 605 x 721 = 60115155870
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
618 : 1, 2, 3, 6, 103, 206, 309, 618
605 : 1, 5, 11, 55, 121, 605
721 : 1, 7, 103, 721
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 223,618,605,721, is 1.
Now, the common factors can be found like this.
223:223
618:2x 3x 103
605:5x 11x 11
721:7x 103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
103 = 103
Therefore, the value for common factors is 103.
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 = 60115155870/(1x103)
LCM = 60115155870/103
LCM = 583642290
Thus, we can understand that the LCM of 223,618,605,721 is 583642290.
