Given numbers are 561,172,494,321

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

The LCM of 561,172,494,321 is 2550187068.

Find LCM of 561,172,494,321 with Prime Factorization

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

2 x 3 x 187 x 86 x 247 x 107 = 2550187068

Therefore, the lowest common multiple of 561,172,494,321 is 2550187068.

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.

561 x 172 x 494 x 321 = 15301122408

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.

561 : 1, 3, 11, 17, 33, 51, 187, 561

172 : 1, 2, 4, 43, 86, 172

494 : 1, 2, 13, 19, 26, 38, 247, 494

321 : 1, 3, 107, 321

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,172,494,321, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

172:2x 2x 43

494:2x 13x 19

321:3x 107

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 15301122408/(1x6)

LCM = 15301122408/6

LCM = 2550187068

Thus, we can understand that the LCM of 561,172,494,321 is 2550187068.
