Given numbers are 647,346,346,349

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

The LCM of 647,346,346,349 is 78127838.

Find LCM of 647,346,346,349 with Prime Factorization

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

2 x 173 x 647 x 1 x 1 x 349 = 78127838

Therefore, the lowest common multiple of 647,346,346,349 is 78127838.

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.

647 x 346 x 346 x 349 = 27032231948

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.

647 : 1, 647

346 : 1, 2, 173, 346

346 : 1, 2, 173, 346

349 : 1, 349

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,346,346,349, is 1.

Now, the common factors can be found like this.

647:647

346:2x 173

346:2x 173

349:349

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

2x 173 = 346

Therefore, the value for common factors is 346.

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 = 27032231948/(1x346)

LCM = 27032231948/346

LCM = 78127838

Thus, we can understand that the LCM of 647,346,346,349 is 78127838.
