Given numbers are 628,654,361,581

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

The LCM of 628,654,361,581 is 43071572796.

Find LCM of 628,654,361,581 with Prime Factorization

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

2 x 314 x 327 x 361 x 581 = 43071572796

Therefore, the lowest common multiple of 628,654,361,581 is 43071572796.

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.

628 x 654 x 361 x 581 = 86143145592

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.

628 : 1, 2, 4, 157, 314, 628

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

361 : 1, 19, 361

581 : 1, 7, 83, 581

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,654,361,581, is 1.

Now, the common factors can be found like this.

628:2x 2x 157

654:2x 3x 109

361:19x 19

581:7x 83

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

2 = 2

Therefore, the value for common factors is 2.

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 = 86143145592/(1x2)

LCM = 86143145592/2

LCM = 43071572796

Thus, we can understand that the LCM of 628,654,361,581 is 43071572796.
