Given numbers are 731,172,481,655

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

The LCM of 731,172,481,655 is 921220820.

Find LCM of 731,172,481,655 with Prime Factorization

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

43 x 17 x 4 x 481 x 655 = 921220820

Therefore, the lowest common multiple of 731,172,481,655 is 921220820.

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.

731 x 172 x 481 x 655 = 39612495260

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.

731 : 1, 17, 43, 731

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

481 : 1, 13, 37, 481

655 : 1, 5, 131, 655

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,172,481,655, is 1.

Now, the common factors can be found like this.

731:17x 43

172:2x 2x 43

481:13x 37

655:5x 131

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

43 = 43

Therefore, the value for common factors is 43.

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 = 39612495260/(1x43)

LCM = 39612495260/43

LCM = 921220820

Thus, we can understand that the LCM of 731,172,481,655 is 921220820.
