Given numbers are 545,81,654

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

The LCM of 545,81,654 is 88290.

Find LCM of 545,81,654 with Prime Factorization

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

3 x 109 x 5 x 27 x 2 = 88290

Therefore, the lowest common multiple of 545,81,654 is 88290.

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.

545 x 81 x 654 = 28870830

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.

545 : 1, 5, 109, 545

81 : 1, 3, 9, 27, 81

654 : 1, 2, 3, 6, 109, 218, 327, 654

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,81,654, is 1.

Now, the common factors can be found like this.

545:5x 109

81:3x 3x 3x 3

654:2x 3x 109

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

3x 109 = 327

Therefore, the value for common factors is 327.

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 = 28870830/(1x327)

LCM = 28870830/327

LCM = 88290

Thus, we can understand that the LCM of 545,81,654 is 88290.

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

• LCM of 727, 35, 896
• LCM of 674, 59, 580
