Given numbers are 25,80,380

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

The LCM of 25,80,380 is 7600.

Find LCM of 25,80,380 with Prime Factorization

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

2 x 2 x 5 x 5 x 4 x 19 = 7600

Therefore, the lowest common multiple of 25,80,380 is 7600.

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.

25 x 80 x 380 = 760000

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.

25 : 1, 5, 25

80 : 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

5 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 25,80,380, is 5.

Now, the common factors can be found like this.

25:5x 5

80:2x 2x 2x 2x 5

380:2x 2x 5x 19

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 760000/(5x20)

LCM = 760000/100

LCM = 7600

Thus, we can understand that the LCM of 25,80,380 is 7600.
