Given numbers are 638,657,346,865

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

The LCM of 638,657,346,865 is 362578590.

Find LCM of 638,657,346,865 with Prime Factorization

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

2 x 173 x 319 x 657 x 1 x 5 = 362578590

Therefore, the lowest common multiple of 638,657,346,865 is 362578590.

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.

638 x 657 x 346 x 865 = 125452192140

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.

638 : 1, 2, 11, 22, 29, 58, 319, 638

657 : 1, 3, 9, 73, 219, 657

346 : 1, 2, 173, 346

865 : 1, 5, 173, 865

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,657,346,865, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

657:3x 3x 73

346:2x 173

865:5x 173

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 = 125452192140/(1x346)

LCM = 125452192140/346

LCM = 362578590

Thus, we can understand that the LCM of 638,657,346,865 is 362578590.
