Given numbers are 43,86,89,903

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

The LCM of 43,86,89,903 is 160734.

Find LCM of 43,86,89,903 with Prime Factorization

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

43 x 1 x 2 x 89 x 21 = 160734

Therefore, the lowest common multiple of 43,86,89,903 is 160734.

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.

43 x 86 x 89 x 903 = 297197166

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.

43 : 1, 43

86 : 1, 2, 43, 86

89 : 1, 89

903 : 1, 3, 7, 21, 43, 129, 301, 903

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 43,86,89,903, is 1.

Now, the common factors can be found like this.

43:43

86:2x 43

89:89

903:3x 7x 43

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

43x 43 = 1849

Therefore, the value for common factors is 1849.

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 = 297197166/(1x1849)

LCM = 297197166/1849

LCM = 160734

Thus, we can understand that the LCM of 43,86,89,903 is 160734.

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

• LCM of 93, 31, 91, 218
