Given numbers are 639,839,223,892
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,839,223,892 is 478219932.
Find LCM of 639,839,223,892 with Prime Factorization
| 223 | 639, 839, 223, 892 |
| 639, 839, 1, 4 |
Multiply the prime numbers at the bottom and the left side.
223 x 639 x 839 x 1 x 4 = 478219932
Therefore, the lowest common multiple of 639,839,223,892 is 478219932.
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.
639 x 839 x 223 x 892 = 106643044836
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.
639 : 1, 3, 9, 71, 213, 639
839 : 1, 839
223 : 1, 223
892 : 1, 2, 4, 223, 446, 892
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,839,223,892, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
839:839
223:223
892:2x 2x 223
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
223 = 223
Therefore, the value for common factors is 223.
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 = 106643044836/(1x223)
LCM = 106643044836/223
LCM = 478219932
Thus, we can understand that the LCM of 639,839,223,892 is 478219932.
