Given numbers are 661,225,375,325
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 661,225,375,325 is 9667125.
Find LCM of 661,225,375,325 with Prime Factorization
| 3 | 661, 225, 375, 325 |
| 5 | 661, 75, 125, 325 |
| 5 | 661, 15, 25, 65 |
| 661, 3, 5, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 5 x 661 x 3 x 5 x 13 = 9667125
Therefore, the lowest common multiple of 661,225,375,325 is 9667125.
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.
661 x 225 x 375 x 325 = 18125859375
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.
661 : 1, 661
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
375 : 1, 3, 5, 15, 25, 75, 125, 375
325 : 1, 5, 13, 25, 65, 325
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,225,375,325, is 1.
Now, the common factors can be found like this.
661:661
225:3x 3x 5x 5
375:3x 5x 5x 5
325:5x 5x 13
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 5x 5 = 1875
Therefore, the value for common factors is 1875.
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 = 18125859375/(1x1875)
LCM = 18125859375/1875
LCM = 9667125
Thus, we can understand that the LCM of 661,225,375,325 is 9667125.
