Given numbers are 286,698,356,138

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

The LCM of 286,698,356,138 is 1225915548.

Find LCM of 286,698,356,138 with Prime Factorization

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

2 x 143 x 349 x 178 x 69 = 1225915548

Therefore, the lowest common multiple of 286,698,356,138 is 1225915548.

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.

286 x 698 x 356 x 138 = 9807324384

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.

286 : 1, 2, 11, 13, 22, 26, 143, 286

698 : 1, 2, 349, 698

356 : 1, 2, 4, 89, 178, 356

138 : 1, 2, 3, 6, 23, 46, 69, 138

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,698,356,138, is 2.

Now, the common factors can be found like this.

286:2x 11x 13

698:2x 349

356:2x 2x 89

138:2x 3x 23

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 = 9807324384/(2x4)

LCM = 9807324384/8

LCM = 1225915548

Thus, we can understand that the LCM of 286,698,356,138 is 1225915548.
