Given numbers are 731,424,489,815

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

The LCM of 731,424,489,815 is 757813080.

Find LCM of 731,424,489,815 with Prime Factorization

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

163 x 731 x 424 x 3 x 5 = 757813080

Therefore, the lowest common multiple of 731,424,489,815 is 757813080.

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 424 x 489 x 815 = 123523532040

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

424 : 1, 2, 4, 8, 53, 106, 212, 424

489 : 1, 3, 163, 489

815 : 1, 5, 163, 815

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,424,489,815, is 1.

Now, the common factors can be found like this.

731:17x 43

424:2x 2x 2x 53

489:3x 163

815:5x 163

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

163 = 163

Therefore, the value for common factors is 163.

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 = 123523532040/(1x163)

LCM = 123523532040/163

LCM = 757813080

Thus, we can understand that the LCM of 731,424,489,815 is 757813080.
