Given numbers are 402,399,137,286

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

The LCM of 402,399,137,286 is 1047452406.

Find LCM of 402,399,137,286 with Prime Factorization

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

2 x 3 x 67 x 133 x 137 x 143 = 1047452406

Therefore, the lowest common multiple of 402,399,137,286 is 1047452406.

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.

402 x 399 x 137 x 286 = 6284714436

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.

402 : 1, 2, 3, 6, 67, 134, 201, 402

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

137 : 1, 137

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 402,399,137,286, is 1.

Now, the common factors can be found like this.

402:2x 3x 67

399:3x 7x 19

137:137

286:2x 11x 13

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 6284714436/(1x6)

LCM = 6284714436/6

LCM = 1047452406

Thus, we can understand that the LCM of 402,399,137,286 is 1047452406.
