Given numbers are 293,731,172,989

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

The LCM of 293,731,172,989 is 19704836.

Find LCM of 293,731,172,989 with Prime Factorization

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

43 x 293 x 17 x 4 x 23 = 19704836

Therefore, the lowest common multiple of 293,731,172,989 is 19704836.

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.

293 x 731 x 172 x 989 = 36434241764

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.

293 : 1, 293

731 : 1, 17, 43, 731

172 : 1, 2, 4, 43, 86, 172

989 : 1, 23, 43, 989

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 293,731,172,989, is 1.

Now, the common factors can be found like this.

293:293

731:17x 43

172:2x 2x 43

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.

43x 43 = 1849

Therefore, the value for common factors is 1849.

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 = 36434241764/(1x1849)

LCM = 36434241764/1849

LCM = 19704836

Thus, we can understand that the LCM of 293,731,172,989 is 19704836.
