Given numbers are 140,342,447

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

The LCM of 140,342,447 is 3567060.

Find LCM of 140,342,447 with Prime Factorization

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

2 x 3 x 70 x 57 x 149 = 3567060

Therefore, the lowest common multiple of 140,342,447 is 3567060.

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.

140 x 342 x 447 = 21402360

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.

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342

447 : 1, 3, 149, 447

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,342,447, is 1.

Now, the common factors can be found like this.

140:2x 2x 5x 7

342:2x 3x 3x 19

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.

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 21402360/(1x6)

LCM = 21402360/6

LCM = 3567060

Thus, we can understand that the LCM of 140,342,447 is 3567060.

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