Given numbers are 202,172,468,278,689
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 202,172,468,278,689 is 14973604308.
Find LCM of 202,172,468,278,689 with Prime Factorization
| 2 | 202, 172, 468, 278, 689 |
| 2 | 101, 86, 234, 139, 689 |
| 13 | 101, 43, 117, 139, 689 |
| 101, 43, 9, 139, 53 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 101 x 43 x 9 x 139 x 53 = 14973604308
Therefore, the lowest common multiple of 202,172,468,278,689 is 14973604308.
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.
202 x 172 x 468 x 278 x 689 = 3114509696064
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.
202 : 1, 2, 101, 202
172 : 1, 2, 4, 43, 86, 172
468 : 1, 2, 3, 4, 6, 9, 12, 13, 18, 26, 36, 39, 52, 78, 117, 156, 234, 468
278 : 1, 2, 139, 278
689 : 1, 13, 53, 689
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 202,172,468,278,689, is 1.
Now, the common factors can be found like this.
202:2x 101
172:2x 2x 43
468:2x 2x 3x 3x 13
278:2x 139
689:13x 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 2x 2x 13 = 208
Therefore, the value for common factors is 208.
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 = 3114509696064/(1x208)
LCM = 3114509696064/208
LCM = 14973604308
Thus, we can understand that the LCM of 202,172,468,278,689 is 14973604308.
