Given numbers are 142,215,731

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

The LCM of 142,215,731 is 519010.

Find LCM of 142,215,731 with Prime Factorization

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

43 x 142 x 5 x 17 = 519010

Therefore, the lowest common multiple of 142,215,731 is 519010.

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.

142 x 215 x 731 = 22317430

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.

142 : 1, 2, 71, 142

215 : 1, 5, 43, 215

731 : 1, 17, 43, 731

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,215,731, is 1.

Now, the common factors can be found like this.

142:2x 71

215:5x 43

731:17x 43

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 = 22317430/(1x43)

LCM = 22317430/43

LCM = 519010

Thus, we can understand that the LCM of 142,215,731 is 519010.

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

• LCM of 654, 595, 280
• LCM of 172, 636, 806
• LCM of 436, 973, 998
