Given numbers are 447,686,708,816

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

The LCM of 447,686,708,816 is 2460495408.

Find LCM of 447,686,708,816 with Prime Factorization

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

2 x 2 x 3 x 149 x 343 x 59 x 68 = 2460495408

Therefore, the lowest common multiple of 447,686,708,816 is 2460495408.

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.

447 x 686 x 708 x 816 = 177155669376

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.

447 : 1, 3, 149, 447

686 : 1, 2, 7, 14, 49, 98, 343, 686

708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708

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 447,686,708,816, is 1.

Now, the common factors can be found like this.

447:3x 149

686:2x 7x 7x 7

708:2x 2x 3x 59

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 3x 3 = 72

Therefore, the value for common factors is 72.

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 = 177155669376/(1x72)

LCM = 177155669376/72

LCM = 2460495408

Thus, we can understand that the LCM of 447,686,708,816 is 2460495408.
