Given numbers are 228,649,621
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 228,649,621 is 30630204.
Find LCM of 228,649,621 with Prime Factorization
| 3 | 228, 649, 621 |
| 76, 649, 207 |
Multiply the prime numbers at the bottom and the left side.
3 x 76 x 649 x 207 = 30630204
Therefore, the lowest common multiple of 228,649,621 is 30630204.
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 649 x 621 = 91890612
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
649 : 1, 11, 59, 649
621 : 1, 3, 9, 23, 27, 69, 207, 621
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 228,649,621, is 1.
Now, the common factors can be found like this.
228:2x 2x 3x 19
649:11x 59
621:3x 3x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 91890612/(1x3)
LCM = 91890612/3
LCM = 30630204
Thus, we can understand that the LCM of 228,649,621 is 30630204.
