Given numbers are 213,687,552,161
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 213,687,552,161 is 62824776.
Find LCM of 213,687,552,161 with Prime Factorization
| 3 | 213, 687, 552, 161 |
| 23 | 71, 229, 184, 161 |
| 71, 229, 8, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 23 x 71 x 229 x 8 x 7 = 62824776
Therefore, the lowest common multiple of 213,687,552,161 is 62824776.
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.
213 x 687 x 552 x 161 = 13004728632
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.
213 : 1, 3, 71, 213
687 : 1, 3, 229, 687
552 : 1, 2, 3, 4, 6, 8, 12, 23, 24, 46, 69, 92, 138, 184, 276, 552
161 : 1, 7, 23, 161
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 213,687,552,161, is 1.
Now, the common factors can be found like this.
213:3x 71
687:3x 229
552:2x 2x 2x 3x 23
161:7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 23 = 207
Therefore, the value for common factors is 207.
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 = 13004728632/(1x207)
LCM = 13004728632/207
LCM = 62824776
Thus, we can understand that the LCM of 213,687,552,161 is 62824776.
