Given numbers are 561,451,336,816

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

The LCM of 561,451,336,816 is 2576112.

Find LCM of 561,451,336,816 with Prime Factorization

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

2 x 2 x 2 x 2 x 3 x 11 x 17 x 1 x 41 x 7 x 1 = 2576112

Therefore, the lowest common multiple of 561,451,336,816 is 2576112.

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 451 x 336 x 816 = 69369543936

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

451 : 1, 11, 41, 451

336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336

816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,451,336,816, is 1.

Now, the common factors can be found like this.

561:3x 11x 17

451:11x 41

336:2x 2x 2x 2x 3x 7

816:2x 2x 2x 2x 3x 17

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

2x 2x 2x 2x 3x 3x 11x 17 = 26928

Therefore, the value for common factors is 26928.

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 = 69369543936/(1x26928)

LCM = 69369543936/26928

LCM = 2576112

Thus, we can understand that the LCM of 561,451,336,816 is 2576112.
