Given numbers are 315,875,157,875
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 315,875,157,875 is 1236375.
Find LCM of 315,875,157,875 with Prime Factorization
| 5 | 315, 875, 157, 875 |
| 5 | 63, 175, 157, 175 |
| 5 | 63, 35, 157, 35 |
| 7 | 63, 7, 157, 7 |
| 9, 1, 157, 1 |
Multiply the prime numbers at the bottom and the left side.
5 x 5 x 5 x 7 x 9 x 1 x 157 x 1 = 1236375
Therefore, the lowest common multiple of 315,875,157,875 is 1236375.
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.
315 x 875 x 157 x 875 = 37863984375
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.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
875 : 1, 5, 7, 25, 35, 125, 175, 875
157 : 1, 157
875 : 1, 5, 7, 25, 35, 125, 175, 875
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,875,157,875, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
875:5x 5x 5x 7
157:157
875:5x 5x 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.
5x 5x 5x 5x 7x 7 = 30625
Therefore, the value for common factors is 30625.
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 = 37863984375/(1x30625)
LCM = 37863984375/30625
LCM = 1236375
Thus, we can understand that the LCM of 315,875,157,875 is 1236375.
