Given numbers are 163,456,751,399

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

The LCM of 163,456,751,399 is 390742296.

Find LCM of 163,456,751,399 with Prime Factorization

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

3 x 19 x 163 x 8 x 751 x 7 = 390742296

Therefore, the lowest common multiple of 163,456,751,399 is 390742296.

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.

163 x 456 x 751 x 399 = 22272310872

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.

163 : 1, 163

456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456

751 : 1, 751

399 : 1, 3, 7, 19, 21, 57, 133, 399

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 163,456,751,399, is 1.

Now, the common factors can be found like this.

163:163

456:2x 2x 2x 3x 19

751:751

399:3x 7x 19

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

3x 19 = 57

Therefore, the value for common factors is 57.

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 = 22272310872/(1x57)

LCM = 22272310872/57

LCM = 390742296

Thus, we can understand that the LCM of 163,456,751,399 is 390742296.
