Given numbers are 326,378,278,209

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

The LCM of 326,378,278,209 is 1789948314.

Find LCM of 326,378,278,209 with Prime Factorization

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

2 x 163 x 189 x 139 x 209 = 1789948314

Therefore, the lowest common multiple of 326,378,278,209 is 1789948314.

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.

326 x 378 x 278 x 209 = 7159793256

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.

326 : 1, 2, 163, 326

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

278 : 1, 2, 139, 278

209 : 1, 11, 19, 209

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 326,378,278,209, is 1.

Now, the common factors can be found like this.

326:2x 163

378:2x 3x 3x 3x 7

278:2x 139

209:11x 19

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 = 7159793256/(1x4)

LCM = 7159793256/4

LCM = 1789948314

Thus, we can understand that the LCM of 326,378,278,209 is 1789948314.
