Given numbers are 81,23,92,253

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

The LCM of 81,23,92,253 is 81972.

Find LCM of 81,23,92,253 with Prime Factorization

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

23 x 81 x 1 x 4 x 11 = 81972

Therefore, the lowest common multiple of 81,23,92,253 is 81972.

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.

81 x 23 x 92 x 253 = 43363188

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.

81 : 1, 3, 9, 27, 81

23 : 1, 23

92 : 1, 2, 4, 23, 46, 92

253 : 1, 11, 23, 253

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 81,23,92,253, is 1.

Now, the common factors can be found like this.

81:3x 3x 3x 3

23:23

92:2x 2x 23

253:11x 23

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

23x 23 = 529

Therefore, the value for common factors is 529.

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 = 43363188/(1x529)

LCM = 43363188/529

LCM = 81972

Thus, we can understand that the LCM of 81,23,92,253 is 81972.

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