Given numbers are 400,155,881,285

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

The LCM of 400,155,881,285 is 622690800.

Find LCM of 400,155,881,285 with Prime Factorization

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

5 x 80 x 31 x 881 x 57 = 622690800

Therefore, the lowest common multiple of 400,155,881,285 is 622690800.

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.

400 x 155 x 881 x 285 = 15567270000

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.

400 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400

155 : 1, 5, 31, 155

881 : 1, 881

285 : 1, 3, 5, 15, 19, 57, 95, 285

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 400,155,881,285, is 1.

Now, the common factors can be found like this.

400:2x 2x 2x 2x 5x 5

155:5x 31

881:881

285:3x 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.

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 = 15567270000/(1x25)

LCM = 15567270000/25

LCM = 622690800

Thus, we can understand that the LCM of 400,155,881,285 is 622690800.
