Given numbers are 490,818,258,478

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

The LCM of 490,818,258,478 is 6178840710.

Find LCM of 490,818,258,478 with Prime Factorization

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

2 x 245 x 409 x 129 x 239 = 6178840710

Therefore, the lowest common multiple of 490,818,258,478 is 6178840710.

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.

490 x 818 x 258 x 478 = 49430725680

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.

490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490

818 : 1, 2, 409, 818

258 : 1, 2, 3, 6, 43, 86, 129, 258

478 : 1, 2, 239, 478

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 490,818,258,478, is 2.

Now, the common factors can be found like this.

490:2x 5x 7x 7

818:2x 409

258:2x 3x 43

478:2x 239

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 49430725680/(2x4)

LCM = 49430725680/8

LCM = 6178840710

Thus, we can understand that the LCM of 490,818,258,478 is 6178840710.
