Given numbers are 423,458,789,368,228
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 423,458,789,368,228 is 178128338832.
Find LCM of 423,458,789,368,228 with Prime Factorization
| 2 | 423, 458, 789, 368, 228 |
| 2 | 423, 229, 789, 184, 114 |
| 3 | 423, 229, 789, 92, 57 |
| 141, 229, 263, 92, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 141 x 229 x 263 x 92 x 19 = 178128338832
Therefore, the lowest common multiple of 423,458,789,368,228 is 178128338832.
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.
423 x 458 x 789 x 368 x 228 = 12825240395904
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.
423 : 1, 3, 9, 47, 141, 423
458 : 1, 2, 229, 458
789 : 1, 3, 263, 789
368 : 1, 2, 4, 8, 16, 23, 46, 92, 184, 368
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 423,458,789,368,228, is 1.
Now, the common factors can be found like this.
423:3x 3x 47
458:2x 229
789:3x 263
368:2x 2x 2x 2x 23
228:2x 2x 3x 19
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 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 12825240395904/(1x72)
LCM = 12825240395904/72
LCM = 178128338832
Thus, we can understand that the LCM of 423,458,789,368,228 is 178128338832.
