Given numbers are 809,436,716,989

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

The LCM of 809,436,716,989 is 62443082444.

Find LCM of 809,436,716,989 with Prime Factorization

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

2 x 2 x 809 x 109 x 179 x 989 = 62443082444

Therefore, the lowest common multiple of 809,436,716,989 is 62443082444.

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.

809 x 436 x 716 x 989 = 249772329776

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.

809 : 1, 809

436 : 1, 2, 4, 109, 218, 436

716 : 1, 2, 4, 179, 358, 716

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 809,436,716,989, is 1.

Now, the common factors can be found like this.

809:809

436:2x 2x 109

716:2x 2x 179

989:23x 43

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 249772329776/(1x4)

LCM = 249772329776/4

LCM = 62443082444

Thus, we can understand that the LCM of 809,436,716,989 is 62443082444.
