Given numbers are 195,21,625

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 195,21,625 is 170625.

Find LCM of 195,21,625 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

3 x 5 x 13 x 7 x 125 = 170625

Therefore, the lowest common multiple of 195,21,625 is 170625.

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.

195 x 21 x 625 = 2559375

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.

195 : 1, 3, 5, 13, 15, 39, 65, 195

21 : 1, 3, 7, 21

625 : 1, 5, 25, 125, 625

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 195,21,625, is 1.

Now, the common factors can be found like this.

195:3x 5x 13

21:3x 7

625:5x 5x 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 5 = 15

Therefore, the value for common factors is 15.

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 = 2559375/(1x15)

LCM = 2559375/15

LCM = 170625

Thus, we can understand that the LCM of 195,21,625 is 170625.
