Given numbers are 745,731,447

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

The LCM of 745,731,447 is 1633785.

Find LCM of 745,731,447 with Prime Factorization

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

149 x 5 x 731 x 3 = 1633785

Therefore, the lowest common multiple of 745,731,447 is 1633785.

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.

745 x 731 x 447 = 243433965

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.

745 : 1, 5, 149, 745

731 : 1, 17, 43, 731

447 : 1, 3, 149, 447

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 745,731,447, is 1.

Now, the common factors can be found like this.

745:5x 149

731:17x 43

447:3x 149

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

149 = 149

Therefore, the value for common factors is 149.

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 = 243433965/(1x149)

LCM = 243433965/149

LCM = 1633785

Thus, we can understand that the LCM of 745,731,447 is 1633785.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 808, 703, 692
