Given numbers are 897,395,445,40

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

The LCM of 897,395,445,40 is 252272280.

Find LCM of 897,395,445,40 with Prime Factorization

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

5 x 897 x 79 x 89 x 8 = 252272280

Therefore, the lowest common multiple of 897,395,445,40 is 252272280.

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.

897 x 395 x 445 x 40 = 6306807000

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.

897 : 1, 3, 13, 23, 39, 69, 299, 897

395 : 1, 5, 79, 395

445 : 1, 5, 89, 445

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 897,395,445,40, is 1.

Now, the common factors can be found like this.

897:3x 13x 23

395:5x 79

445:5x 89

40:2x 2x 2x 5

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 6306807000/(1x25)

LCM = 6306807000/25

LCM = 252272280

Thus, we can understand that the LCM of 897,395,445,40 is 252272280.
