Given numbers are 867,521,654,545

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

The LCM of 867,521,654,545 is 492360630.

Find LCM of 867,521,654,545 with Prime Factorization

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

3 x 109 x 289 x 521 x 2 x 5 = 492360630

Therefore, the lowest common multiple of 867,521,654,545 is 492360630.

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.

867 x 521 x 654 x 545 = 161001926010

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.

867 : 1, 3, 17, 51, 289, 867

521 : 1, 521

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

545 : 1, 5, 109, 545

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 867,521,654,545, is 1.

Now, the common factors can be found like this.

867:3x 17x 17

521:521

654:2x 3x 109

545:5x 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 = 161001926010/(1x327)

LCM = 161001926010/327

LCM = 492360630

Thus, we can understand that the LCM of 867,521,654,545 is 492360630.
