Given numbers are 228,905,288,860
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 228,905,288,860 is 212942880.
Find LCM of 228,905,288,860 with Prime Factorization
| 2 | 228, 905, 288, 860 |
| 2 | 114, 905, 144, 430 |
| 3 | 57, 905, 72, 215 |
| 5 | 19, 905, 24, 215 |
| 19, 181, 24, 43 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 19 x 181 x 24 x 43 = 212942880
Therefore, the lowest common multiple of 228,905,288,860 is 212942880.
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.
228 x 905 x 288 x 860 = 51106291200
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.
228 : 1, 2, 3, 4, 6, 12, 19, 38, 57, 76, 114, 228
905 : 1, 5, 181, 905
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 228,905,288,860, is 1.
Now, the common factors can be found like this.
228:2x 2x 3x 19
905:5x 181
288:2x 2x 2x 2x 2x 3x 3
860:2x 2x 5x 43
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 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 51106291200/(1x240)
LCM = 51106291200/240
LCM = 212942880
Thus, we can understand that the LCM of 228,905,288,860 is 212942880.
