Given numbers are 631,940,865,785

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

The LCM of 631,940,865,785 is 16110275540.

Find LCM of 631,940,865,785 with Prime Factorization

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

5 x 631 x 188 x 173 x 157 = 16110275540

Therefore, the lowest common multiple of 631,940,865,785 is 16110275540.

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.

631 x 940 x 865 x 785 = 402756888500

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.

631 : 1, 631

940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940

865 : 1, 5, 173, 865

785 : 1, 5, 157, 785

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,940,865,785, is 1.

Now, the common factors can be found like this.

631:631

940:2x 2x 5x 47

865:5x 173

785:5x 157

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

5x 5 = 25

Therefore, the value for common factors is 25.

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 = 402756888500/(1x25)

LCM = 402756888500/25

LCM = 16110275540

Thus, we can understand that the LCM of 631,940,865,785 is 16110275540.
