Given numbers are 189,424,647,921,212
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 189,424,647,921,212 is 15917333544.
Find LCM of 189,424,647,921,212 with Prime Factorization
| 2 | 189, 424, 647, 921, 212 |
| 2 | 189, 212, 647, 921, 106 |
| 3 | 189, 53, 647, 921, 106 |
| 53 | 63, 53, 647, 307, 106 |
| 63, 1, 647, 307, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 53 x 63 x 1 x 647 x 307 x 2 = 15917333544
Therefore, the lowest common multiple of 189,424,647,921,212 is 15917333544.
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.
189 x 424 x 647 x 921 x 212 = 10123424133984
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
424 : 1, 2, 4, 8, 53, 106, 212, 424
647 : 1, 647
921 : 1, 3, 307, 921
212 : 1, 2, 4, 53, 106, 212
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,424,647,921,212, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
424:2x 2x 2x 53
647:647
921:3x 307
212:2x 2x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 53 = 636
Therefore, the value for common factors is 636.
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 = 10123424133984/(1x636)
LCM = 10123424133984/636
LCM = 15917333544
Thus, we can understand that the LCM of 189,424,647,921,212 is 15917333544.
