Find LCM of 375,225,209,450 with Prime Factorization
| 3 | 375, 225, 209, 450 |
| 3 | 125, 75, 209, 150 |
| 5 | 125, 25, 209, 50 |
| 5 | 5, 25, 209, 10 |
| 1, 5, 209, 2 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 5 x 1 x 5 x 209 x 2 = 470250
Therefore, the lowest common multiple of 375,225,209,450 is 470250.
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.
375 x 225 x 209 x 450 = 7935468750
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.
375 : 1, 3, 5, 15, 25, 75, 125, 375
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
209 : 1, 11, 19, 209
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 375,225,209,450, is 1.
Now, the common factors can be found like this.
375:3x 5x 5x 5
225:3x 3x 5x 5
209:11x 19
450:2x 3x 3x 5x 5
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 5x 5x 5 = 16875
Therefore, the value for common factors is 16875.
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 = 7935468750/(1x16875)
LCM = 7935468750/16875
LCM = 470250
Thus, we can understand that the LCM of 375,225,209,450 is 470250.
