Given numbers are 228,623,490,288
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 228,623,490,288 is 119316960.
Find LCM of 228,623,490,288 with Prime Factorization
| 2 | 228, 623, 490, 288 |
| 2 | 114, 623, 245, 144 |
| 3 | 57, 623, 245, 72 |
| 7 | 19, 623, 245, 24 |
| 19, 89, 35, 24 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 19 x 89 x 35 x 24 = 119316960
Therefore, the lowest common multiple of 228,623,490,288 is 119316960.
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 623 x 490 x 288 = 20045249280
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
623 : 1, 7, 89, 623
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 228,623,490,288, is 1.
Now, the common factors can be found like this.
228:2x 2x 3x 19
623:7x 89
490:2x 5x 7x 7
288:2x 2x 2x 2x 2x 3x 3
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 7 = 168
Therefore, the value for common factors is 168.
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 = 20045249280/(1x168)
LCM = 20045249280/168
LCM = 119316960
Thus, we can understand that the LCM of 228,623,490,288 is 119316960.
