Given numbers are 286,119,646,423

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

The LCM of 286,119,646,423 is 273531258.

Find LCM of 286,119,646,423 with Prime Factorization

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

2 x 17 x 143 x 7 x 19 x 423 = 273531258

Therefore, the lowest common multiple of 286,119,646,423 is 273531258.

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 119 x 646 x 423 = 9300062772

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

119 : 1, 7, 17, 119

646 : 1, 2, 17, 19, 34, 38, 323, 646

423 : 1, 3, 9, 47, 141, 423

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 286,119,646,423, is 1.

Now, the common factors can be found like this.

286:2x 11x 13

119:7x 17

646:2x 17x 19

423:3x 3x 47

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 9300062772/(1x34)

LCM = 9300062772/34

LCM = 273531258

Thus, we can understand that the LCM of 286,119,646,423 is 273531258.
