Given numbers are 861,448,163,406

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

The LCM of 861,448,163,406 is 260476608.

Find LCM of 861,448,163,406 with Prime Factorization

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

2 x 7 x 123 x 32 x 163 x 29 = 260476608

Therefore, the lowest common multiple of 861,448,163,406 is 260476608.

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.

861 x 448 x 163 x 406 = 25526707584

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.

861 : 1, 3, 7, 21, 41, 123, 287, 861

448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448

163 : 1, 163

406 : 1, 2, 7, 14, 29, 58, 203, 406

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 861,448,163,406, is 1.

Now, the common factors can be found like this.

861:3x 7x 41

448:2x 2x 2x 2x 2x 2x 7

163:163

406:2x 7x 29

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

2x 7x 7 = 98

Therefore, the value for common factors is 98.

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 = 25526707584/(1x98)

LCM = 25526707584/98

LCM = 260476608

Thus, we can understand that the LCM of 861,448,163,406 is 260476608.
