Given numbers are 631,706,805,811,905

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

The LCM of 631,706,805,811,905 is 52641635017930.

Find LCM of 631,706,805,811,905 with Prime Factorization

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

5 x 631 x 706 x 161 x 811 x 181 = 52641635017930

Therefore, the lowest common multiple of 631,706,805,811,905 is 52641635017930.

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 706 x 805 x 811 x 905 = 263208175089650

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

706 : 1, 2, 353, 706

805 : 1, 5, 7, 23, 35, 115, 161, 805

811 : 1, 811

905 : 1, 5, 181, 905

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 631,706,805,811,905, is 1.

Now, the common factors can be found like this.

631:631

706:2x 353

805:5x 7x 23

811:811

905:5x 181

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

5 = 5

Therefore, the value for common factors is 5.

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 = 263208175089650/(1x5)

LCM = 263208175089650/5

LCM = 52641635017930

Thus, we can understand that the LCM of 631,706,805,811,905 is 52641635017930.
