Given numbers are 125,375,321
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 125,375,321 is 40125.
Find LCM of 125,375,321 with Prime Factorization
| 3 | 125, 375, 321 |
| 5 | 125, 125, 107 |
| 5 | 25, 25, 107 |
| 5 | 5, 5, 107 |
| 1, 1, 107 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 5 x 5 x 1 x 1 x 107 = 40125
Therefore, the lowest common multiple of 125,375,321 is 40125.
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.
125 x 375 x 321 = 15046875
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.
125 : 1, 5, 25, 125
375 : 1, 3, 5, 15, 25, 75, 125, 375
321 : 1, 3, 107, 321
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 125,375,321, is 1.
Now, the common factors can be found like this.
125:5x 5x 5
375:3x 5x 5x 5
321:3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 5 = 375
Therefore, the value for common factors is 375.
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 = 15046875/(1x375)
LCM = 15046875/375
LCM = 40125
Thus, we can understand that the LCM of 125,375,321 is 40125.
