Given numbers are 642,101,865,865

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

The LCM of 642,101,865,865 is 56088330.

Find LCM of 642,101,865,865 with Prime Factorization

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

5 x 173 x 642 x 101 x 1 x 1 = 56088330

Therefore, the lowest common multiple of 642,101,865,865 is 56088330.

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.

642 x 101 x 865 x 865 = 48516405450

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

101 : 1, 101

865 : 1, 5, 173, 865

865 : 1, 5, 173, 865

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,101,865,865, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

101:101

865:5x 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.

5x 173 = 865

Therefore, the value for common factors is 865.

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 = 48516405450/(1x865)

LCM = 48516405450/865

LCM = 56088330

Thus, we can understand that the LCM of 642,101,865,865 is 56088330.
