Given numbers are 489,225,630,147
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 489,225,630,147 is 3594150.
Find LCM of 489,225,630,147 with Prime Factorization
| 3 | 489, 225, 630, 147 |
| 3 | 163, 75, 210, 49 |
| 5 | 163, 25, 70, 49 |
| 7 | 163, 5, 14, 49 |
| 163, 5, 2, 7 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 163 x 5 x 2 x 7 = 3594150
Therefore, the lowest common multiple of 489,225,630,147 is 3594150.
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.
489 x 225 x 630 x 147 = 10189415250
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.
489 : 1, 3, 163, 489
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
147 : 1, 3, 7, 21, 49, 147
3 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 489,225,630,147, is 3.
Now, the common factors can be found like this.
489:3x 163
225:3x 3x 5x 5
630:2x 3x 3x 5x 7
147:3x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 5x 7 = 945
Therefore, the value for common factors is 945.
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 = 10189415250/(3x945)
LCM = 10189415250/2835
LCM = 3594150
Thus, we can understand that the LCM of 489,225,630,147 is 3594150.
