Given numbers are 557,939,629,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 557,939,629,221 is 4276759071.
Find LCM of 557,939,629,221 with Prime Factorization
| 17 | 557, 939, 629, 221 |
| 557, 939, 37, 13 |
Multiply the prime numbers at the bottom and the left side.
17 x 557 x 939 x 37 x 13 = 4276759071
Therefore, the lowest common multiple of 557,939,629,221 is 4276759071.
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.
557 x 939 x 629 x 221 = 72704904207
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.
557 : 1, 557
939 : 1, 3, 313, 939
629 : 1, 17, 37, 629
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 557,939,629,221, is 1.
Now, the common factors can be found like this.
557:557
939:3x 313
629:17x 37
221:13x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17 = 17
Therefore, the value for common factors is 17.
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 = 72704904207/(1x17)
LCM = 72704904207/17
LCM = 4276759071
Thus, we can understand that the LCM of 557,939,629,221 is 4276759071.
