Given numbers are 189,300,695,315
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 189,300,695,315 is 2627100.
Find LCM of 189,300,695,315 with Prime Factorization
| 3 | 189, 300, 695, 315 |
| 3 | 63, 100, 695, 105 |
| 5 | 21, 100, 695, 35 |
| 7 | 21, 20, 139, 7 |
| 3, 20, 139, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 7 x 3 x 20 x 139 x 1 = 2627100
Therefore, the lowest common multiple of 189,300,695,315 is 2627100.
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.
189 x 300 x 695 x 315 = 12413047500
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.
189 : 1, 3, 7, 9, 21, 27, 63, 189
300 : 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300
695 : 1, 5, 139, 695
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 189,300,695,315, is 1.
Now, the common factors can be found like this.
189:3x 3x 3x 7
300:2x 2x 3x 5x 5
695:5x 139
315:3x 3x 5x 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 5x 7 = 4725
Therefore, the value for common factors is 4725.
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 = 12413047500/(1x4725)
LCM = 12413047500/4725
LCM = 2627100
Thus, we can understand that the LCM of 189,300,695,315 is 2627100.
