Given numbers are 286,249,406,290

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

The LCM of 286,249,406,290 is 72282210.

Find LCM of 286,249,406,290 with Prime Factorization

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

2 x 29 x 143 x 249 x 7 x 5 = 72282210

Therefore, the lowest common multiple of 286,249,406,290 is 72282210.

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 249 x 406 x 290 = 8384736360

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

249 : 1, 3, 83, 249

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

290 : 1, 2, 5, 10, 29, 58, 145, 290

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,249,406,290, is 1.

Now, the common factors can be found like this.

286:2x 11x 13

249:3x 83

406:2x 7x 29

290:2x 5x 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 2x 29 = 116

Therefore, the value for common factors is 116.

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 = 8384736360/(1x116)

LCM = 8384736360/116

LCM = 72282210

Thus, we can understand that the LCM of 286,249,406,290 is 72282210.
